EN ↔ JP comparison · which version to grade
Grade the Japanese Mew ex, or the English one?
Which to grade: Both are PSA 10 chases on a ~30% gem rate, not safe sends. The Japanese 205 SAR has the bigger ceiling — a ~10× PSA 10 on a ¥3,000 raw — but the same low odds; the English 193 is a thinner ~3.4×. Chasing the 10, the Japanese has more upside, but a PSA 9 erases the margin on either.
Side-by-side of the same card in both languages. Graded figures are recent sold medians (eBay); raw is the TCGplayer / market reference. Gem rates are labeled estimates. As of 2026-06-28. example/mock data
