I like the way you think Cy, but don't forget, the 0-number series includes other athletes and boxers... That numbering system doesn't really help baseball subject collecting IMO. I also don't see a good reason to renumber a 2500+ card set just because a few have a number at the top. And lastly, coming from a struggling collector

, trying to break the set down by year makes collecting the set too difficult. I personally like the way it is, it's not hard I figure out what year a card was first produced, and whether or not it was produced other years. (using the OJ bible, of course)
I'll also add that there is a zero-number checklist in the back of the book.
