I have a run, 1948 and 1951 to 2011. I can understand not including 1948, which is a subset of a larger set, and if it is included why not the 55 and 56 Hocus Focus sets ( I have 56 done but only 10 or so of the 55s).
But, I do think 1951 sets should be included....all 5 of them
( less the 3 unissued Current All Stars...because I don't have them
)
I have done the traded sets as well...and the Heritage sets for fun....and those great big Total Baseball sets
And an unopened pack for each year and any variation listed in the SCD Big Book
