Why TAG 10 is outselling PSA 10 on the Masaki Promo Gengar

A collector reported that on May 19, 2026, a TAG-graded Masaki Promo Gengar in a 10 holder sold above the contemporaneous PSA 10 comp on the same card. We have not independently verified the sale, and it is the first we have seen reported for this card rather than a market-wide first — check it on 130point before you price anything on it.

For collectors who default to PSA as the only "real" grader, this is a meaningful inflection. TAG's machine-graded sub-scores (centering, surface, edges, corners — each on a 0–10 scale, computed by their imaging rig) have steadily gained acceptance over the last 24 months, especially with collectors who distrust subjective grading. The Masaki Gengar sale is the moment that acceptance crossed the threshold where TAG can hold price parity with PSA on a flagship vintage card.

What we shipped in response

The OWNED /graders page now publishes our cross-grader normalization table — the typical market multiple of each grader's gem grade vs PSA 10 of the same card:

• PSA 1.00× (benchmark)
• TAG 0.85× (range 0.55–1.10×) — growing acceptance
• BGS 0.80× (range 0.55–1.10×) — Pristine + Black Label can premium PSA on vintage
• CGC 0.55× (range 0.40–0.70×)
• SGC 0.55× — niche, thin liquidity
• AGS 0.55× — same discount as CGC per the data we have

These are starting priors derived from collector observation and auction comps. Per-card variance is real and large — always verify on 130point or /comp before pricing.

Data ingestion gap (being honest)

Our pricing data today tracks PSA-graded comps. TAG and AGS sale data lives scattered across eBay listings, 130point queries, and Whatnot streams — it is not yet auto-ingested. Expanding the normalization layer from "starting priors" to "per-card live data" requires a dedicated TAG/AGS comp scraper. That's on the roadmap.
