There is a Davy Crockett pack on eBay currently and here is the description given by the seller:"1956 Topps Davy Crockett unopened wax pack. Sent to PSA but they wouldn't slab it because the gum was broken. Pack is legit and unopened with 3 of 4 corner splits from the loose gum. Super rare pack."I've never heard this before. Is PSA rejecting broken gum or is this just an excuse?
