Gem-rate trap: >80% grade PSA 10, so the grade is common, not a chase

Positive grading EV is the problem — it funds an ever-growing PSA 10 supply

~8-month-old card (Nov 2025) — population velocity, not just level, is the tell

JP price ceiling keeps falling: PSA 10 accepted sales ~$216, down from ~$290

Public track record

5 graded: 1 hit, 4 misses · early sample · nothing backdated

Same serial, different cards

ST21-014 · 2 variants

This serial spans $204 to $1,942. The price apps show one number for all of them — that's the trap.

Every price above is variant-matched — a real sold-comp median where the card trades, a model fair value (est) where it hasn't. Never a blended average across the serial. Why one number has several prices →

Why $204

median of 3 PSA 10 sold · as of Sep 15, 2026

PSA 10 One Piece Magazine Vol.20 promo — the graded premium this AVOID is about, priced on the JP market where it trades natively. Raw copies now ask ~$126 (a fine collectible); the 80%+ gem rate keeps pumping PSA 10 supply.

Why we believe it

Own it raw, don't chase it graded. The tell isn't the 36,828 PSA 10 population — it's that 80%+ of graded copies come back PSA 10: the top grade is the default outcome, not an achievement, so it carries no real scarcity. That turns the ~$100 raw → PSA 10 gap (shown above) into an open arbitrage — grade for ~$20, expect a 10 four times in five — which pumps ever more PSA 10s into supply. Released only Nov 2025, the raw pool is nowhere near drained, and Japan now clears PSA 10 at ~$216 (SNKRDUNK, ten accepted sales), and the premium has kept deflating exactly as this call predicted — down from $300 in July. Its fixed magazine print gives it a floor (dead money, not a falling knife), but there is no appreciation case here. Avoid the PSA 10 as an investment; the ~$100 raw is a fine collectible. Founder holds raw — disclosed; this call is on the graded premium, not the cheap raw.

The other side

  • Collectibles are high-variance — demand can cool and prices can fall.
  • Graded population grows over time, which can soften high-grade premiums.
  • Population figures shown here are illustrative until the live pipeline lands.
