Note that most of the evidence may suggest that coins of the same player seem to have been issued with the same color back. Those listed as "variations" with different color backs may have had the coin popped out some time in it's history and re-seated in a different color, rather than originating that way from the factory.

Note that besides the various color backs, there are also "SAVE 180" and "SAVE AND TRADE 200" versions of back text, as the set was expanded later in the run.
