I have been in this hobby for years. I have always added any type of errors I could to my Yankees collection. Wrong backs, wrong name, no name, no foil anything different. One of these flaws I includes blank backs or fronts. Now in the last couple years any blank backs listed are titled "proofs". Is there any truth to this? Are these blank backs in any way a part of the printing process or meant for a promo or is it just a flaw by the companies part? Even Topps Vault sells blank back and lists them as proofs. What's your take on these?
