Picked up a very unique Cobb M101-3 PC a couple years ago raw at The National. Showed it to numerous collectors and auction houses. No one I spoke to including Bill Mastro has ever seen a Sporting News M101-3 with an advertisement on the verso. Last M101-3 Cobb sold at Heritage for $40k+. Recently graded by SGC 1.5 because it has been postally used. Otherwise looks like a solid 3.5. No creases! Looking for an offer.
