One Collector Paid $2,063 for a PSA 10 Mew ex. Three Weeks Later It Sold for $540.

The first PSA 10 of the 30th Celebration Mew ex sold for $2,063 at auction on Sept. 27. Nineteen days later, another sold for $540.

The drop came fast. Eleven more PSA 10s sold from Oct. 5 to 17. The eight auctions among them since Oct. 9 closed between $540 and $820.

Raw copies sold 102 times from Oct. 17 to 19. More of them will come back from PSA as 10s in the weeks ahead.

The $2,063 bought the first slab on the market. With a PSA 10 now selling at auction most days, we'd bid near $600.
