2007 Upper Deck Sweet Spot Classic Baseball Forum

Can somebody please explain how the base set of 200 cards has numbers 35, 75 & 164 missing?  Didn’t know base sets could have omissions since it’s usually inserts and parallels that have omissions.  I’ve been in search for 3 years of a Ron Guidry from this base set where 575 copies are supposed to be in existence when all I have found are the memorabilia item instead which exist on eBay as a 12:0 right now for the ratio of finding the memorabilia item over the base item so seems like there might not be 575 copies out there of the bass set for each card.  Just my two cents and seeing if anybody has any details regarding this base set.  Thanks in advance. 

The 2011 SCD has those 3 card numbers as not printed. I put it off to weird times in the industry, everything from licensing, to exclusive player deals with companies, companies trying to get product out the door with poor quality control, etc.
