HCI vs COMC: How HobbyCardIndex and COMC Compare in 2026
Two quick pointers before the breakdown. If your real question is whether a card is worth sending in for grading before you route it to COMC, our grading decision framework walks the cost math card by card. And if you're weighing COMC as one of several venues for turning cards into cash, our rundown of the alternatives to CardLadder maps where the pricing platforms fit alongside the marketplaces.
What HCI and COMC actually do
HobbyCardIndex and COMC both get named in card-selling conversations, but they sit in different corners of the hobby, and the moment you open either one you can feel it. COMC, short for Check Out My Cards, is a consignment marketplace that has been running since 2007 out of Redmond, Washington. Its center of gravity is inventory. A seller ships cards in, COMC processes and scans them, each card gets a fixed-price listing on comc.com, many of those listings also cross-post to eBay through COMC's feed, and buyers hit either surface to buy.
HCI sits on the research side. Its center of gravity is the per-card pricing page. Sold-comp prices separated by grade, PSA and BGS population counts, per-sport and per-grade indexes, trend math, and an editorial layer of guides, hubs, and reports sitting on top. We built it for the moments when you want to think about a card, what it's worth right now, how it's moved, and whether a listing at COMC's asking-price band is actually sane, rather than the moment you want to physically move a stack of cards through a consignment pipeline.
So the two products are not substitutes. COMC handles inventory logistics for a seller who does not want to hand-list every card. HCI helps that same seller price the cards fairly before they hand them off, and helps a buyer decide whether a COMC asking price actually reads as market. I'd guess most collectors who touch the long tail of the hobby end up using both, and that pairing reads as the honest answer rather than a forced pick.
The HCI vs COMC feature matrix
The table below covers the surfaces collectors weigh when picking between, or combining, the two products. Treat the COMC column as directionally accurate as of . Marketplace terms, per-card processing fees, and storage bands shift with policy changes, so verify the current schedule directly with COMC ahead of any consignment.
| Feature | HobbyCardIndex | COMC |
|---|---|---|
| Primary purpose | Sold-price tracking, market trends, indexes, grading decision support | Consignment marketplace with fixed-price listings and eBay cross-listing |
| Business model | Free per-card research, paid tier for portfolio and alerts | Per-card processing fee, sale commission, storage on unsold inventory |

Where does the money go on a five hundred dollar sale?
Fee stacks are the part collectors often get wrong, and COMC's stack has more moving parts than a straight sale on an open marketplace. The math changes materially by card value, seller tier, and whether the card is sitting on inventory or moving on the first list. To keep it concrete, the table below runs a hypothetical five hundred dollar graded modern rookie sale through five common venues so you can see roughly where the net cash lands. Treat every row as directional and confirm current fees with each venue before you commit.
| Venue | Fee stack, rough | Net to seller, rough |
|---|---|---|
| COMC direct sale | Per-card processing near two dollars, seller cut close to a fifth of the sale, plus any storage or port at cash-out | Around three hundred ninety eight dollars if the card sits on inventory briefly, less if storage stacks |
| eBay BIN or Best Offer | Final value fee near thirteen and a quarter percent, small per-order fee, seller ships | Around four hundred thirty three dollars after fees, before shipping cost |
| PWCC Premier auction | Consignment fee bands typically fifteen to twenty percent on non-vault cards | Around four hundred to four hundred twenty five dollars after commission |
| Local card shop counter | Shop pays a percentage of sold-comp median, usually sixty to seventy percent for graded modern | Around three hundred to three hundred fifty dollars, in cash, same day |
| MySlabs fixed price | Marketplace fee near five percent plus payment processing near three percent | Around four hundred sixty dollars after fees, seller ships |
Two things worth pinning down from that table. First, COMC and PWCC Premier land in a similar net band on a mid-market graded rookie, but they solve different jobs. PWCC's number comes from a curated auction event with marketing lift, and COMC's number comes from a fixed-price listing that sits on the platform until a buyer pulls it. Our HCI vs PWCC comparison walks the Weekly Auction, Marketplace, and Delaware Vault economics in detail and models the four-venue take-home math on a hypothetical $2,500 vintage card if that upper-tier venue is on your shortlist. Second, the local card shop counter looks bad on the net column but delivers cash same day with zero shipping risk, which is a real feature for a seller who wants to be done. The math on paper is only half the picture.
The HCI job in this decision is the pre-flight check. Look up the card, note the per-grade median, subtract the fee stack you would expect at each venue, and compare the net figure against how fast you actually want to move the card. We keep the methodology behind those numbers once at our methodology page, and the how-to for reading them is in our guide on how to value a card.
Do COMC listings show up in HCI comps?
Active COMC asking prices do not flow into HCI's sold-comp pool. The pool is sold-side only, aggregated through trusted pricing partners, and an asking price on a live COMC listing is not a sold record. That distinction matters. A seller listing a card at COMC for four hundred dollars is not the same market signal as a seller who actually cleared four hundred dollars on that same card last week. HCI reads the second one, not the first.
Where the two products do touch is through the eBay cross-listing pipe. When a COMC card is set up to also list on eBay through COMC's feed, and that eBay listing actually sells, the resulting sold record can flow into the wider sold-comp pool the same way any other eBay sale does. The card page on HCI does not know or care that the seller was COMC, only that a real hammer cleared at a real price. That flow is slower than the on-platform view, usually a week or two behind, and it applies only to the subset of COMC inventory that actually cross-lists and sells.
The practical thing that this means for a buyer is that a COMC asking price is a data point about a seller's confidence, not a data point about market clearing. Cross-check the asking price against the HCI per-grade median before you buy, and look at how the sale count has moved over the last ninety days. If the COMC ask is well above the HCI median for that grade, either the seller is stretching, or the card has moved and the sold pool has not caught up yet. The next real sale will tell you which.
When is COMC actually the right tool?
Consignor economics is the part collectors often get wrong on COMC, so it's worth walking through carefully. The per-card processing fee plus commission plus optional storage looks steep on a single mid-value card, but the model earns its keep on batches of cards a solo seller cannot realistically hand-list. A collector who has a shoebox of raw ninety through two hundred dollar cards can ship the whole shoebox in, let COMC scan and list every card, and get to a state where every card is discoverable to buyers without a night of one-by-one listing work. That workflow lift is the real product.
The rough default is that COMC fits inventory in the roughly ten to a couple hundred dollar band per card, in enough volume that the processing fee reads as a workflow charge rather than a hit, and where the seller has time on their side. A card that has to move this month is a bad fit for a marketplace that lives on browsing traffic. Cards that will happily sit for a quarter or two while the right buyer walks by are a good fit. Higher-value cards, in the thousand-plus band, usually net more on a fixed-price marketplace with lower fees or a curated auction venue.
The HCI job in that picture is triage before the shipment. Look up every card, sort by per-grade median, and route the highest-value cards to a lower-fee venue while the long tail heads to COMC. Under a dollar or two a card the calculus shifts again toward a checklist-driven singles site, which is the ground our Sportlots comparison covers, fee ladder and per-seller postage included. That is a different question from what any single card is worth, and it is the one HCI is built to answer at portfolio scale.
Who should pick which
| Collector profile | Recommended first | Why |
|---|---|---|
| Researching a card before buying | HobbyCardIndex | Sold-only methodology, per-grade medians, dated quotes |
| Consigning a shoebox of long-tail inventory | COMC | Scan-and-list pipeline earns its keep at volume |
| Selling a top-end rookie or vintage card | Auction house or fixed-price marketplace | COMC fee stack eats the ceiling on high-value single cards |
| Deciding whether to grade before consigning | HobbyCardIndex | Per-grade comps and EV math, plus the grading guides |
| Tracking portfolio value over time | HobbyCardIndex | Portfolio, alerts, per-grade indexes at the paid tier |
| Buying a set-build filler card | COMC | Long-tail inventory density and consolidated shipping |
| Combined workflow (research on HCI, sell on COMC) | Both | HCI for the price triage, COMC for the long-tail listings |
The table is a default, not a verdict. Most portfolio sellers I know use a research tool for the triage and pick a venue based on the specific card. Which research tool is a separate question, and our HCI vs CardLadder and HCI vs TCDB pages cover those. If you want to see how COMC compares to another marketplace-shaped venue, our HCI vs Cardbase comparison covers the mobile scan-first angle, and HCI vs Goldin covers the auction house end of the spectrum.
Marketplace and independence
One structural note worth flagging is the broader question of who is earning what when a price gets published. HCI does not run a marketplace, a grading service, a breaking business, or a card-manufacturing line, and we take no affiliate fees from graders. The structure is documented on our independence page. The reason we keep it that way is that pricing data should not be entangled with a business that profits from price direction or transaction volume.
COMC is a different shape by design. It is a marketplace, so its revenue comes from processing fees, sale commissions, and cash-out fees, which means COMC benefits from listings moving and cards changing hands. That is the correct incentive for a marketplace and a good reason to cross-check a listing price against an independent research tool before you buy or set an ask. Neither incentive is bad, they just answer different questions.
How should you read the HCI vs COMC choice?
The short version is that HCI and COMC are not a versus. They are a workflow. COMC is the venue for moving the mid-tail cards that would otherwise sit unlisted for months, and HCI is the research tool for deciding on a fair price per card and whether any given card belongs in the COMC pipeline at all. Reading them as competitors just gets you to a bad answer on both sides.
If your bottleneck is figuring out where a card should be trading right now, how it has moved over the last year, whether the per-grade spread justifies grading, or whether the sold-comp pool supports a listing price, that is HCI's job, and an asking price on COMC on its own does not cover it. If your bottleneck is actually converting a stack of long-tail cards into cash without a night of hand-listing, that is COMC's job, and a research page does not do that for you. Plenty of collectors run HCI for the numbers and COMC for the listings, and that combination usually beats forcing one product into a job it was not built for.
One honest caveat to close on. We have described COMC from public information and the wider consignment marketplace category, and marketplace terms and fee bands shift often, so check the current schedule and consignor requirements with COMC directly before you ship cards in. This page is a comparison, not investment advice, and it is not a recommendation to buy, sell, or consign any card.
Bottom line
Common questions about HCI vs COMC
Is HobbyCardIndex a COMC alternative?
Not really. COMC is a consignment marketplace that lists your cards for sale on comc.com and via cross-listings on eBay. HobbyCardIndex is a research platform that shows sold-comp pricing per card and per grade. COMC moves cards. HCI tells you what one should trade at.
What is the main difference between HCI and COMC?
COMC is a marketplace where sellers ship cards in, COMC scans and lists them, buyers pay COMC or a cross-listing. HobbyCardIndex is a research tool with per-grade sold comps, population counts, and per-card indexes. COMC's job is to sell your card. HCI's job is to price it before you list.
How much does COMC charge sellers?
COMC's public seller fee stack typically includes a per-card processing fee in the roughly one to three dollar range plus a sale cut around a fifth of the hammer, with storage and cash-out fees layered on unsold inventory. Rates shift by tier and card value, so confirm the current schedule with COMC directly. HobbyCardIndex charges nothing to look up a comp.
Do COMC asking prices show up in HobbyCardIndex comps?
Asking prices do not. HCI's sold-comp pool is aggregated through trusted pricing partners on the sold side of the market. When a COMC card cross-lists to eBay and actually sells, that sold hammer can flow into the wider pool a week or two later. Active COMC asks stay on COMC.
Should I consign my card to COMC or sell it myself?
The rough rule is COMC fits bulk cards a seller would rather ship out in one shipment than photograph individually, in the roughly one to two hundred dollar band, where the processing fee and commission are worth the time saved. Higher-value cards usually net more on a fixed-price marketplace or an auction house. Run the math on the HCI comp minus fees before consigning.
Is COMC trustworthy for buying cards?
COMC has been running the consignment marketplace model since 2007 out of Redmond, Washington, with a large scanned inventory and public buyer records. Trust still comes down to reading the scan, checking the card condition through the front and back images, and confirming your all-in cost after shipping and any port fees.
Can I use HCI and COMC together?
That pairing is the intended flow. Use HCI to see where the sold comp sits per grade, whether the card belongs in a COMC list price band, and what a fair asking price is after the fee stack. Then use COMC as the venue if the card fits the long-tail marketplace shape.
