$7,542
Huge jump · last 2 sales about 4.0 times the 2 before
Estimated from this grade's 3 sales of the last year
Only 3 of its sales are from the last 90 days. A full estimate needs 5.
- Recent sales: middle of the last 3: $7,542, Aug 23 to Oct 2
- Evidence: limited · 3 sales we counted in the last 90 days · last sale Oct 2
- Sold this past year: $3,800 to $8,850 as paid
Updated Oct 20, 2026. Estimate and recent sales (the sold range is as paid): all adjusted to typical eBay auction prices.
How close we came: half of 7,682 sales were within 19 percent of our estimate the day before. Group: EX era, fewer than 5 sales in 90 days, Jan 1, 2025 to Oct 18, 2026. See how close we came for similar grades
How we got this
Fewer than 5 sales we counted in 90 days and too little related data for a modeled figure, so this is the plausibility-weighted median of this grade's own 3 sales in the last 365 days, each moved to today by how this era's prices have changed since it sold. A sale far from the others counts for less.
Recent sales broke from the earlier level, so the estimate restarted from them on Oct 2 (2 sales since). It stays at limited evidence until 5 sales since.
Recent sales: the middle (median) of the last 3 sales we counted (Aug 23 to Oct 2), each adjusted to typical eBay auction prices: Buy It Now and auction-house prices are moved by the gap we measure between venues in this era. The sales list shows the prices paid.
Checked on 7,682 estimate-to-next-sale pairs for grades with fewer than 5 sales in 90 days, EX era, from Jan 1, 2025 to Oct 18, 2026: half the next sales landed within 19 percent of the estimate at the time (as of Oct 20). A record of past estimates, not a guarantee for this card.
Estimates with limited evidence had a median error of 22 percent on 44,262 past cases (Jan 1, 2025 to Oct 16, 2026).
Sales in the last 90 days ran from $3,800 (Aug 23) to $8,850 (Oct 2) (3 sales, prices paid).
Last sale Oct 2, 2026 (18 days ago). Since then, EX sales have run 14 percent above their previous prices.
Evidence: strong means at least 4.5 effective recent sales (older and clustered sales count for less) with a spread under 0.15; moderate, at least 2.8 with a spread under 0.30; limited, anything less. The basis (sales of this grade, or estimated from similar cards) is stated separately.

Huge jump
The last 2 sales, Sep 26 to Oct 2, were about 4.0 times the 2 sales before them.
Our estimate has moved part of the way: $4,367 on Sep 25, $7,542 now.
What this label means
The latest 2 or more sales in a row came in the last 60 days. Each sold for at least 2 times the earlier price. Each is also more than 2.5 times the usual spread above it.
The earlier price is the middle sale of this grade in the 180 days before these sales.
The usual spread is how much this grade's price moves from one sale to the next.
Labels describe past sales only. They never change our estimate.

About this chart
Log scale: the highest sale is more than 4 times the lowest, so equal steps on the price axis are equal percentage changes.
Buy It Now and auction-house prices are moved by the gap we measure between venues in this era, so every dot is comparable with an eBay auction. Tap a dot to see the price paid.
No sales in the last 7 days; the last sale was $8,850 paid, 18 days ago. Last 30 days: 2 sales, too few to compare. Last 90 days: 3 sales, middle sale $7,542 adjusted. Last 12 months: 3 sales, $3,800 to $8,850 paid. Of 3 other grades with 5 or more sales in 90 days, 2 rose and 1 fell. Movement label since Sep 26, 2026: Huge jump.

How we got this
This text is built each night from the sales shown on this page, last on Oct 20, 2026. It is a record of what happened, not a forecast. Every number in it is checked against the stored facts before it is shown.
Each window's middle sale is the middle of its sales, once as paid and once adjusted. A change compares the adjusted middle sale with the window of the same length just before it, and only when both have 3 or more sales. Our estimate's change uses the figure the site showed on the window's first day.

How we got this
eBay: the estimate plus the shipping you charge, less eBay's fee on both, less the per-order fee and your postage. The Buy It Now row uses the Buy It Now estimate. Fanatics, Goldin and Alt auctions: the estimate moved to that venue's prices with the gap we measure for this era, divided by one plus the buyer's premium to get the hammer price, then the seller bonus added or the commission taken off, less postage. Fanatics Buy Now and Alt fixed price: that venue's price less its seller fee and postage. Card show: the range dealers often pay for a card of this value, higher for grades that sell often and lower for grades that rarely sell (see Methodology); the figure used to rank it is the middle of that range, or the estimate times your percentage. With your own price, every place takes it as what the buyer pays, and an auction's hammer is that price less the buyer's premium. Sales tax is left out; eBay also charges its fee on tax the buyer pays. fees as of Oct 19, 2026.
- eBay auction: Trading card fee: 13.25% of the sale up to $7,500. Above that, 2.35% on the rest. The sale counts the price, shipping charged and sales tax. Each order also pays $0.30, or $0.40 over $10. Sales tax is left out here. Checked Oct 19, 2026 (confirmed). Source
- eBay Buy It Now: Same fees as the auction, on the Buy It Now estimate. That is our estimate times this era's usual Buy It Now gap, never below the estimate. Checked Oct 19, 2026 (confirmed). Source
- Fanatics auction: Buyers pay a 20% premium on the hammer price. Our stored Fanatics prices include that 20%. Premier Auction, for cards worth $25,000 or more: the seller gets 110% of the hammer. That rises to 112.5% above $250,000 and 115% above $1,000,000. Weekly Auction: a bonus of 2% to 15% on sales of $50 or more. We use the lowest, 2%. There is no seller fee. Checked Oct 19, 2026 (partly confirmed). Source
- Fanatics Buy Now: Seller fee 6% when listed under 120% of Card Ladder's market value. It is 12% at or above that. Buyers pay no fee. We list at the Fanatics price, so 6% applies. Checked Oct 19, 2026 (confirmed). Source
- Goldin auction: Buyers pay a 22% premium, at least $19. Goldin does not publish its seller commission. About 5% is a typical figure, not confirmed. We do not measure Goldin prices yet, so this route has no figure. Checked Oct 19, 2026 (partly confirmed). Source
- Alt auction: Buyers pay a 20% premium. Sellers pay no fee. The base seller bonus depends on the card's value: 4% under $1,000, 6% to $5,000, 8% to $25,000. It is 10% to $50,000, 12% to $200,000 and 15% above. We use the hammer price for the value. We assume our stored Alt prices include the premium. Checked Oct 19, 2026 (confirmed). Source
- Alt fixed price: Base seller fee: 14% to $249, 9% to $7,499, 7% to $9,999, and 5% from $10,000. Buyers pay no fee. Checked Oct 19, 2026 (confirmed). Source
- Show offer: No fee. Your own percentage of the estimate. The default follows the evidence: 87.5% strong, 80% moderate, 67.5% limited. Checked not checked (not applicable).
Grades · CGC · Holo
Grades 8 to 8.5 share one estimate so a lower grade never shows above a higher one.
Grades 3.5 to 4.5 share one estimate so a lower grade never shows above a higher one.
Estimates are adjusted to typical eBay auction prices. Sold ranges are prices as paid. A dash in the 30-day change column means no change is shown: it needs strong or moderate evidence.
How we got this
A grade's estimate needs 5 or more sales we counted in 90 days; otherwise the panel shows the lowest to highest sale of the last year. When neighbouring grades' sales overlap, or a lower grade's figure would sit above a higher grade's, they share one precision-weighted estimate (each figure weighted by how tight its range is). The 30-day change compares with the last settled estimate and shows only with strong or moderate evidence.
