Hi Jim,
Its been a few years since I activly collected Baseball cards, so I don't have an updated Becketts Guide around, But I would venture to say that I don't have any chips in my humble collection that would be worth the trade!

My dad once told me the story of how all his 1950's cards had been thrown away by his mom when he went off to the Army. Mantle, Koufax, Stan the Man, Williams, etc... breaks my heart!!!

Regards,
Jim
