I have them classified as W-Unc since they were cut out. If we say they are in fact candy cards then R-Unc would be more appropriate than E-Unc, since they would be "recent candy". I have never heard of anyone going for a set of them. I have never seen any other stamps on back except the 2 mentioned, as seen here. Neat type cards....
Very recently I did measure them up against the regular S and S cards and they are only about 1/16" of an inch wider, from what I remember.....but it is a very distinct 1/16". The width of the regular game cards would definitely not vary, as opposed to many other pre-war cards.
