The 63 plaque/mask was something i placed strong bid on back in the REA auction 2013, but i settled on 2 other lots..I know it had the 'tab' intact and fetched more than the 5k i wanted, if i remember it reached 7k.
One of the board members gladly has one and shows it once in a while with a wood frame border. I can tell you that the plastic frame of the card is very brittle they say and careful of the nose to not break off. if i not mistaken, there was one on Ebay at one time.
Now for the 61 Dice Game...yeah its the #1 most valuable it seems.
One of the other sites (COMC) i think has a top 5 list what people think are most valuable Mantle cards.
61 Dice Game, 63 plaque/mask, 55 test stamps (which may be claim as 56), then a 70 topps cloth (which also is uncertain) then 66 topps punch-out, then maybe a 59 Bazooka
