I'd guess that, right now, at pre-reprint prices, the total expect value of a box of Ultimate Masters is probably close to $500, maybe a touch more, which makes Ultimate Masters the single most valuable (and perhaps best, depending on how you define "best") set ever printed
If the title mentions Holo or Reverse Holo, that's what you'll receive
The Obsidian Flames and Paldean Fates sets further reignited interest in Fire-type Pokmon cards, and the Scarlet & Violet 151 set now out of print has become a modern collector classic, driving sustained price appreciation
This feels like a non-answer to me @markrosewater
Instead of the familiar flat plastic and cardboard damage tabs, Classic includes three-dimensional cone-shaped damage markers with additional stackable rings to designate special conditions
