If you complete the trade with Tony I have this offer. I would trade the card pictured for the 4 common T205 cards I PMed you about earlier and the Pete Rose/Ron Santo single signed baseballs from the trade with Tony.
This is the 5th card Beckett ever graded and a great piece of Beckett history. It is from the companies internal test run of 10 cards before any cards were graded for the public. This is super cool/special because it is a card of Jim Beckett III the founder of Beckett. From my understanding 3 of the 10 original cards graded are the Jim Beckett III Topps Stadium of Stars cards.
As far as value, I value it the same as 4 common T205's and 2 single signed baseballs.
