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 $20 - no sale of this Purple Letters at PSA 7 yet: precision-weighted average of 3 measured estimates - [1] from this card's PSA 8 value ($32, 3 sales, newest Nov 5, 2025) x 0.71 (measured PSA 7/8 curve (gpk_vintage, at $32)) | [2] From this card's Blue Letters PSA 9 sales (8 sales, recency-weighted $9, newest Jun 25, 2025), moved to PSA 7 by the measured GPK grade ratio, converted to base through its own ladder step x 1.56, the measured ratio of variant parallels to their base card (1481 GPK card pairs; 1481 in vintage GPK (1985-90)), at a $<25 base price and today's parallel premium; 90% range 1.5-1.6x; 3 anchors on this card combined. | [3] its set: 418 sale-backed other cards, 1 of them Purple Letters, x 1.0 the measured unnumbered-to-base ratio across GPK cards (23354 sales in that band), less the measured never-sold discount (21%) ($18); raised to $20, the sale-backed Purple Letters PSA 6 (an estimate never sits under a measured lower grade).

🗑️ The Garbologist says…

Too Thin To Call
Straight from the Garbologist's clipboard:
  • 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.

BORDERLINE

Roughly a 18.8% gem rate on this card's own PSA pop - graded pop is self-selected (best copies get submitted), so a random raw likely grades lower. Expected ~$112 before the $80 PSA fee (fee only - excludes shipping & insurance), ~$32 after - about even with a raw copy ($17 from 13 raw sales). A coin flip that only pays off on a high grade.
