I was looking thru a bunch of Main Street Station Players Gold cards - They all looked the same to me - except 1 caught my eye- this one has numbers by where it says insert this end -startig with the letter P#### then at the bottom it says CARD CURRENCY - for a acct # it's 000##### on the back resv.# is all X out and replaced to the left - I can see it is not a regular player's card but what was it used for - myself I don't collect these -
