I know that the Reds aren't the Yankees, but I think it might be possible to glean some info from the Keymen site that may be helpful :

For Yankees tickets, the only year that has "Rain Check" in a large box, and were printed by Ansell-Simplex Ticket Co. is 1951.
Could mean something, but maybe not.
I'm also thinking that the tax amounts could provide some clues.
