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!

I believe psa is the only major company that grades pins. I have a few of those Quaker Oats Ruth pins myself I would love to have graded but hate the thought of sending them there for months and months of waiting.
