PSA vs BGS vs SGC Subgrades: How They Differ in 2026
PSA does not show subgrades on the slab. BGS shows four subgrades on every label, with Black Label requiring all four at 10 and Gold Label requiring all four at 9.5+. SGC shows subgrades on request and runs from 1 through 10 Pristine. Crossover and regrade math depends entirely on the subgrade distribution, not just the overall.
Subgrade selection drives crossover decisions, regrade EV, and liquidity on premium-tier cards. Before paying any submission fee, run the candidate through the grading decision framework, then use this guide to pick the grader whose methodology fits the card and the buyer pool.
The four subgrade categories all three graders evaluate
Every modern grade is built up from four sub-categories. The graders weight them slightly differently and present them differently on the label, but the categories themselves are consistent.
- Centering. Front and back centering measured against the printed border. PSA-10 modern centering tolerance is roughly 55/45 to 60/40 on the front, 75/25 on the back. BGS publishes specific tolerance bands per grade (50/50 for 10, 55/45 for 9.5, etc.). SGC is roughly aligned with PSA on tolerance.
- Corners. All four corners under magnification. Sharp, white-free, no fuzz, no rounding. A single soft corner caps the grade at 8 or 9 across all three graders.
- Edges. Top, bottom, left, right edges of the card, including any color-border chipping or whitening visible under angled light.
- Surface. Print lines, scratches, indentations, foil disturbance, surface haze. Foil-front cards are particularly sensitive on this category.
The overall grade is roughly the lowest of the four subgrades for PSA and SGC, with some weighting on corners and centering. BGS uses a more visible weighting formula where the overall grade is allowed to be 0.5 above the lowest subgrade if the other three are clearly higher (this is why a BGS card can be a 9.5 overall with one 9 subgrade).
PSA: no subgrades on the slab
PSA's standard grade is one number from 1 to 10 displayed on the slab label. The full subgrade evaluation happens internally, but the result is condensed to the overall.
PSA does offer subgrades as an add-on service: the "PSA Subgrades" certification adds an additional document with the centering, corners, edges, and surface scores reported separately. The fee is roughly 30 USD per card on top of the base submission tier (Vintage tier and above only as of April 2026), and the subgrades are NOT printed on the slab. They exist as a separate certification document tied to the cert number.
The result is that the secondary market on PSA cards trades almost entirely on the overall grade. A PSA 10 is a PSA 10. The only differentiator inside the same overall grade is the cert number range (lower-numbered older cert holders carry a slight collector premium on flagship rookies because of the perception that older cert numbers reflect tighter grading) and the holder generation (the current Lighthouse holder is the standard since 2022).
PSA 10 vs PSA 9 multiplier examples
| Card | PSA 9 median | PSA 10 median | Multiple |
|---|---|---|---|
| 1986 Fleer Michael Jordan #57 | ~$2,800 | ~$15,000 | 5.4x |
| 2009-10 Topps Chrome Stephen Curry RC | ~$1,200 | ~$5,500 | 4.6x |
| 2018 Panini Prizm Luka Doncic base RC | ~$260 | ~$900 | 3.5x |
| 2020 Panini Prizm Justin Herbert base RC | ~$60 | ~$210 | 3.5x |
| 2011 Topps Update Mike Trout RC | ~$300 | ~$1,400 | 4.7x |
| 1999 SP Authentic Roy Halladay FW /500 | ~$500 | ~$1,600 | 3.2x |
| 1989 Upper Deck Ken Griffey Jr. RC | ~$30 | ~$160 | 5.3x |
The 9-to-10 multiplier on PSA runs roughly 3 to 5x across most modern rookies and 4 to 6x on vintage Hall of Fame names. Cards with very thin PSA 10 supply can clear higher multiples; junk-wax-era stars with massive PSA 10 pop counts can compress to 2.5x or lower.
BGS: subgrades on the label, Black Label and Gold Label tiers
BGS prints all four subgrades on the front of every slab. The label shows the overall grade in a large numeral and the four subgrades (Centering, Corners, Edges, Surface) below it. The Black Label and Gold Label tiers are designations layered on top:
- BGS Black Label (Pristine 10). Overall 10 AND all four subgrades 10. The rarest BGS designation, often described as "perfect" by collectors. PSA-10-equivalent pricing on a Black Label runs 2-5x the comparable PSA 10 on most modern cards.
- BGS Gold Label (9.5). Overall 9.5 AND all four subgrades 9.5 or higher. Common premium tier above standard BGS 9.5. PSA-10-equivalent pricing runs 1.4-1.7x the comparable PSA 10.
- BGS 9.5 (Gem Mint). Standard premium grade. Pricing typically 0.7-0.9x of comparable PSA 10 on the same card unless the subgrades make a Gold Label or near-Gold Label case.
- BGS 9 (Mint). Compares to PSA 9 on pricing, with slight discount because of buyer-pool size differences (PSA pool is larger).
BGS subgrade reading: how to interpret a 9.5 with mixed subgrades
Two cards both labeled "BGS 9.5" can have very different secondary-market pricing. The subgrade distribution tells the story.
| Subgrades C/Co/E/S | Designation | Pricing vs PSA 10 |
|---|---|---|
| 9.5 / 9.5 / 9.5 / 9.5 | Gold Label (all four 9.5) | 1.4-1.7x |
| 10 / 9.5 / 9.5 / 10 | 9.5 with strong subs (one off-Gold) | 0.95-1.15x |
| 9.5 / 9.5 / 9 / 9.5 | 9.5 with one 9 (edges-pulled) | 0.7-0.85x |
| 10 / 10 / 9 / 9.5 | 9.5 with one 9 (edges-pulled, two 10s elsewhere) | 0.85-1.0x; regrade upside if edge fixable |
| 9.5 / 10 / 10 / 9 | 9.5 with one 9 (surface-pulled) | 0.65-0.8x; surface 9 rarely upgrades |
The subgrade with the lowest score is what a buyer prices off, not the overall. A 9 on edges is recoverable in some cases (edge whitening that responds to Mylar pressing); a 9 on surface is usually permanent (a print line or scratch is not removable).
SGC: subgrades on request, vintage authentication strength
SGC's standard grade is one number from 1 to 10 displayed on the slab. SGC offers subgrade reports as an add-on, though the take-rate among SGC submitters is lower than BGS because the SGC market is more vintage-weighted and vintage buyers historically focus on overall grade and authenticity over subgrade granularity.
- SGC Pristine 10. Top grade. Equivalent to PSA 10 in market function, generally trading at 80-95 percent of comparable PSA 10 on modern cards and at parity or above on pre-1980 vintage where SGC's authentication track record carries.
- SGC 10. Standard 10 (one notch below Pristine 10). Trades at 70-85 percent of comparable PSA 10 on modern; vintage parity holds.
- SGC 9.5. Mint+ tier. Trades roughly at PSA 9.5-equivalent levels, which is roughly 0.5-0.7x comparable PSA 10.
- SGC 9. Mint. Trades roughly at PSA 9 levels.
SGC's strength is vintage. The Tuxedo holder design, the SGC vintage-grader bench, and the historical pricing data on pre-1980 cards graded by SGC create a stable parity-or-better outcome on cards from before 1980. For modern cards (post-2000), SGC trades at a discount to PSA because the modern buyer pool defaults to PSA pop reports.
Cross-grader pricing matrix (April 2026)
| Grade | PSA | BGS | SGC |
|---|---|---|---|
| Pristine / Black Label / Pristine 10 | n/a (PSA 10 is top) | $2,000-$5,000 (Black Label) | $800-$950 (Pristine 10) |
| 10 / 9.5 Gold / 10 | $1,000 (PSA 10 baseline) | $1,400-$1,700 (Gold Label) | $700-$850 |
| 9 / 9.5 Standard / 9.5 | $220-$300 (PSA 9) | $700-$900 (BGS 9.5) | $500-$650 (SGC 9.5) |
| 8 / 9 / 9 | $120-$160 | $220-$300 | $200-$280 |
The numbers are reference points; the actual ratio for any specific card depends on supply at each grade tier. Cards with high PSA 10 pop counts compress the BGS Black Label premium toward 2x; cards with thin PSA 10 supply can push the Black Label premium to 5x or beyond.
Crossover math: when to move a card between graders
Crossover is the process of submitting an already-graded card to a different grading service in its current slab, with the request that the new grader either match or exceed the current grade (otherwise the card is returned in the original slab). All three services offer crossovers in both directions, with fees roughly equivalent to the standard tier plus a small crossover surcharge.
The crossover decision math:
- BGS 9.5 (standard, no Gold) to PSA 10: typically positive EV if the BGS card has 9.5 or higher subgrades on corners and centering. Crossover success rate at PSA 10 on a standalone BGS 9.5 runs roughly 30-50 percent. Failed crosses return the card in the BGS slab.
- BGS Black Label to PSA 10: typically negative EV. Black Label trades above PSA 10 already, so the cross only helps if the buyer pool you are targeting (Asian markets, modern card collectors) heavily prefers PSA over BGS regardless of subgrade.
- SGC 10 to PSA 10: typically positive EV on modern cards; typically neutral on vintage. Crossover success at PSA 10 runs roughly 40-60 percent on a clean SGC 10.
- PSA 10 to BGS Black Label: typically negative EV. PSA 10 cards rarely cross to Black Label because the BGS subgrade math requires all four 10s, which is a higher bar than PSA's overall 10 standard.
Crossover failure outcomes matter. A failed cross returns the card in the original slab with no grade change, but the cross attempt cost the fee. Budget for a 30-50 percent failure rate on most crossovers.
Which grader for which card
| Card category | Best grader | Why |
|---|---|---|
| Modern star rookie (NBA, NFL, MLB) | PSA | Largest buyer pool; pop reports tracked; PSA 10 is the price anchor |
| Modern parallel or short print with extreme centering | BGS | Black Label/Gold Label premium pays for the centering tolerance |
| Pre-1980 vintage star | PSA or SGC | SGC vintage authentication track record; PSA pop dominance |
| Vintage with grade 6-7 condition | SGC | SGC vintage market dominance at lower grades; Tuxedo holder collector preference |
| Pokemon WOTC holo | PSA or CGC | PSA 10 is the price anchor; CGC has gained share on modern Pokemon |
| Modern Pokemon (2020+) | CGC or PSA | CGC 10 trades within a few percent of PSA 10 on Sword and Shield era; Pristine 10 designation is collector-recognized |
| Premium autographed card with extreme centering | BGS | Black Label premium on signed cards is real, plus auto subgrade |
| Sealed pack or sealed box | CGC or BBCE for boxes | BGS has weaker sealed-product authentication track record |
BGS autograph subgrade (the fifth sub)
BGS adds a fifth sub-category for cards that include an on-card or sticker autograph: the Auto subgrade. The Auto subgrade is rated 1-10 and reflects the quality of the signature itself (boldness, placement, smudging). The Auto subgrade does NOT factor into the overall grade calculation; it is reported separately on the slab.
The Auto subgrade matters for buyer pricing on autographed cards. A BGS 9.5 card with a 10 Auto trades at a measurable premium to the same overall grade with a 9 Auto. Sticker autographs typically receive 9 or 10 (the sticker is consistent); on-card autographs vary more (a faded or small autograph can score 8 or below even on a clean surface).
Frequently asked questions
Does PSA give subgrades?
PSA does not list subgrades on the standard slab. PSA's overall grade (1 through 10) is the only number on the front of the label. PSA's internal review process does evaluate the four sub-categories (centering, corners, edges, surface), and these can be requested as a separate document on Vintage tier or above for an additional fee, but they are not displayed on the slab itself.
What is a BGS Black Label?
BGS Black Label is a BGS 10 Pristine where all four subgrades (centering, corners, edges, surface) are also 10. It is the rarest BGS designation and trades at meaningful premiums (typically 2-5x a standard BGS 9.5 on the same card). The Gold Label is a BGS 9.5 with all four subgrades at 9.5 or higher, which is also a premium designation but more common than Black Label.
How does an SGC Pristine 10 compare to a PSA 10?
SGC Pristine 10 is SGC's top grade and is roughly equivalent to a PSA 10 in market terms, with SGC trading at 80-95 percent of the comparable PSA 10 sold price on most modern cards. SGC's vintage market presence is strongest on pre-1980 cards, where SGC graded examples often trade at parity or above PSA on the same grade because of the SGC vintage authentication track record.
Should I cross a card from BGS to PSA for the higher comp?
The crossover-grade math depends on whether your BGS 9.5 is also a Black Label or Gold Label. A standalone BGS 9.5 typically clears more value crossed to PSA 10 (when the cross succeeds). A BGS Black Label is usually worth more in its current slab than as a PSA 10. Cross-over fees, the variance of the cross attempt, and the loss of the original holder all factor in; review the math against the specific card's PSA 10 sold comp before submitting for crossover.
Why do collectors care about subgrades on a 9.5 instead of just calling it a 9.5?
Two BGS 9.5 cards can have very different subgrade profiles. One might be 9.5/9.5/9.5/9.5 (a Gold Label, near-Pristine), and another might be 10/9.5/9/9.5 (which scores lower on edges and pulls the overall down). Buyers paying premium pricing on a BGS 9.5 want to see all four subgrades because the eventual crossover prospect, the Black Label upgrade chance on regrade, and the liquidity all depend on the subgrade distribution, not just the overall.
