2011 leaf pop century

Each card in this series is autographed and is usually accompanied by parallel versions 
(highlighted in silver or gold). Base autographs are not serial numbered, while the silver, gold, 
and blue versions were. Blue-highlighted cards were exclusive to the 2011 National Sports Collectors 
Convention, where packs holding printing-plate cards from either the 2011 release or the 2010 
Razor edition were also sold. Further information and scans are posted at the Leaf website.

Leaf announced specific cards as "Short Prints" and these are identified as "SP" in the list. 
Some of the short-prints were found only in numbered editions. An "unn" in the lists means 
that the card has been observed in an unnumbered version, i.e., not as "x/25" or the equivalent. 
Some variants may exist but have not been observed yet. Printing plates have been observed 
for most cards, and I expect that they were distributed for all. Plates are signed for the single-
person cards, but were unsigned for dual and triple autographed cards. Leaf announced that 
the Shannon Elizabeth cards were not included in the release. Several of the scarcest items are 
shown on the Leaf checklist but have not yet been observed in the aftermarket, so the numbers 
made aren't known (but are probably small).
