Mega Latias ex PSA 10 value: is the slab worth 4.09× a raw copy?
A 4.09× multiple, or a ¥7,555 gap, is the grading premium over the ¥2,444 raw on the live listings re-checked on 2026-10-29. The PSA 9 at ¥7,999 sits ¥2,000 below the cheapest live PSA 10 — a self-submission that misses PSA’s GEM MT 10 standard[6] and lands a 9 is worth roughly that much less on this page’s listings, before grading fees and two-way shipping. For most buyers the finished ¥9,999 slab is the simpler route to a 10; check the label (088/063, PSA 10) and the cert number in the seller photos before you buy.
| Route | Cost today (JPY, before shipping) | What you get |
|---|---|---|
| Buy the cheapest PSA 10 slab | ¥9,999 | Grade already locked in; you pay the full premium, nothing to wait for. |
| Buy the cheapest raw copy as-is | ¥2,444 | Lowest-cost route on this page; condition is whatever the photos show (seller note: “Unused”). |
| Buy the cheapest raw copy with Mercari official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity) | ¥4,144 | ¥2,444 + ¥1,700 authentication fee[1], only if the seller has enabled it on that Mercari listing; Mercari official issues its conclusion before the card ships (OneMall does not guarantee authenticity), but it is still ungraded. |
Buy the ¥9,999 slab after checking the label and cert number in the photos. For the binder, the ¥2,444 “Unused” raw (¥4,144 all-in with Mercari official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity)[1], if the seller has enabled it). The ¥7,999 PSA 9 only makes sense if a 9 is all you need.
