Grading vintage pins?
Hey folks -
I've got a handful of vintage pins I'd love to grade, if possible. I have no idea if there is a service that handles 1930s Crackerjack pins (PR4) and others. I have a 1940 Walter Johnson for Congress pin as well as 1934 Babe Ruth Quaker Oats pin. Anyone have advice on this? Thanks in advance!
Matt
