After ITG went out of business they took all the leftover jersey and autograph cards from their warehouse, stamped them with a bunch of different coloured "V" logos, and sold them off in the "Final Vault" product referenced previously (five jersey cards, four autographed cards, and one Goalie Mask card per box). The same card may exist with up to 10 different coloured "V 1 of 1" stamps, and any jersey or auto card ITG ever produced could theoetically exist in stamped "Final Vault" versions so compiling complete checklists is impossible.
In my experience most collectors and dealers don't differentiate the stamped versions of the cards from the original unstamped versions, and they don't carry any price premium (or penalty) over the regular cards.
