A PSA 10 1983 Topps Nolan Ryan #360 is valued at about $1,950, a price-guide estimate rather than a recorded-sales median. Its 40 recorded PSA 10 sales in the last year ranged from $744 to $2,310; they have not yet passed Slabline's checks (a sharp price move, a wide spread, or possibly another printing's sales), so the value shown stays on the price guide until they do. At other grades it is valued at about $58 (Raw / Ungraded), $22 (Grade 7), $31 (Grade 8).

How to read this page: an estimate is Slabline's figure for a grade, built from the source named beside it. An observed price is the latest price a grader's copy of this card fetched, one cell per grader and grade in the grid below. A recorded sale is a dated transaction with its venue. The headline above is the estimate for this slab's own grade.

A dealer typically pays about 30% of market for a fast, guaranteed sale — the rest is the liquidity gap. An auction or private sale can recover more but takes time and fees. It’s why your Slabline Score weighs liquidity — and why insuring at market matters: a fire-sale recovers far less than the number you’re covered for.
Estimated from dealer buy-vs-sell spreads; actual offers vary by condition and demand.
