But at some point Sporting Life began to repackage some cards again in team sets. This is why you find some cards with the 300 Series backs which were originally issued in low series with one of the other backs. Oddly, the envelopes for these series have numbers above 50, which means some kind of numbering code was in effect, since there were apparently no Series 25-50. Unlike the envelopes for 1-24, the envelopes for the team sets don't contain a list of the players included, only the team name, so it's basically impossible to assign these Team set cards to a series. And I'm not sure there's a lot of point to doing so anyway.
But as far as Series 1-24 go, each card appears in one and only one series.
Sounds complicated but that is the best I can do to clarify. The parenthetical numbers from Lew's article (seen in the image above) are accurate with about 5 exceptions.
Scott is right-- the Seymour variation is also missing from Lew's list.
