GPK Price Guide Value iThis card has no sale at this grade yet, so the value is an estimate from its other grades and from cards like it, and it is labelled as an estimate until it sells. How this one was worked out: Estimate $39 - no sale of this Black /99 at PSA 10 yet: geometric mean of 2 measured estimates - [1] From this card's Xfractor PSA 10 sales (2 sales, recency-weighted $29, newest Jan 14, 2026), converted to base through its own ladder step x 2.95, the measured ratio of 51-99 numbered parallels to their base card (347 GPK card pairs; 38 in GPK Chrome / Bowman), at a $<25 base price and today's parallel premium; 90% range 2.6-3.6x; 7 anchors on this card combined. | [2] its set: 53 sale-backed other cards, 4 of them Black /99, x 1.7 the measured 51-99 numbered-to-base ratio across GPK cards (1354 sales in that band), less the measured never-sold discount (21%) ($32). Order law: moved from $30 to $40 to keep print-run order with this card's other parallels; moved from $40 to $39 to keep print-run order with this card's other parallels.

🗑️ The Garbologist says…

Too Thin To Call
The Garbologist has been digging through this one's trash.
  • Nobody's actually sold this exact card and grade on record, so there's no live market to read — the price you see is a modeled estimate, not a realized sale.
  • With this little to go on, the honest answer is we can't call a direction — one auction would swing the whole read.

Automated analysis generated from this card’s real recorded sales and PSA population data — no opinions, no predictions guaranteed. Entertainment and research only, not financial advice.

SAVE YOUR MONEY

Only a 26.2% gem rate on the 2023 GPK PSA pop (all sets that year) - graded pop is self-selected (best copies get submitted), so a random raw likely grades lower. Expected ~$17 before the $80 PSA fee (fee only - excludes shipping & insurance), ~-$63 after - near or below a raw copy ($33 (guide value, not a sale)). Not worth grading unless you are confident it is a 10.
