Completed sales from UK-located eBay sellers, in pounds, newest first. Raw and graded sales are listed together, so this total is wider than the per-condition price above, which is the middle of each condition’s most recent 10. Market reference, not sales on TheGemMint.

Price history

We’re building price history from confirmed UK sold listings: real sales, in pounds, in this market. It appears on a card once there are enough of them.

Grading

Condition guide: what to look for

A reference when pricing or evaluating your own copy.

PSA 10Top tier
Gem Mint

Perfect 4-corner centring (typically 55/45), no whitening, no surface scratches under angled light. Pop & cert verifies on PSA's lookup.

PSA 9Strong
Mint

One minor flaw: slight centring drift or one minuscule corner mark visible under loupe. Surface still clean. Strong eye-appeal.

PSA 8Mid tier
Near Mint–Mint

Slight wear on one or two corners, minor surface marks, or noticeable centring (~65/35). Holo still pops.

Raw NMBaseline
Near Mint (ungraded)

Pulled and stored well, sleeved straight from the booster. Strong PSA 9–10 candidate but ungraded, so the buyer takes the grading risk.

  1. £1.17Raw, Moderately Played·sold 28 Jun

Not a market price: with fewer than 3 UK sales each one is shown as it happened. Confirmed eBay UK sold listings.

The market price is the middle of the most recent 10 UK sold listings within the last 90 days, after unusually high or low sales are set aside. A Best Offer sale is shown at its asking price and left out of the price when 5 or more other sales remain. A condition or grade with fewer than 3 UK sales shows each sale instead of a price. Market reference, not sales on TheGemMint. Last checked 26 Sept 2026 (may be out of date).
