Official Statement from Topps: “An exchange was inserted into packs for Jake Mauer‘s autographed RC. The exchange card was intended to be card number 388 in the checklist, but the actual Mauer autograph mailed out to collectors was card number 324. Thus, this set actually has two cards numbered 324 (the Jake Mauer autograph and a basic issue Ben Broussard card) and no number 388.”
