Ya know what? I'm gonna jump in here. Many of you know me... I've been collecting vintage material--both baseball and historical--since 1961. I've always been happy to provide my opinion (a very educated opinion, but an opinion, nonetheless) gratis--either here on the board or privately. But, I recently retired (nobody told me not to quit my day job!), and I could use a few extra bucks.
So... for a PayPal charge of $5, I'll provide a "quick opinion.' If I don't feel qualified to judge a particular piece, I'll let you know that, too, upfront.
No certs, no bullshit paper. I'll let you know whether or not I think it's good.
You take it from there.
