Interested in the Mountcastle XR Auto, it books $30, the 2021 Elite Purple #18 Ryan Mountcastle $6, and the 2021 Diamond Kings Debut Diamond Kings Plum Frame #3 Ryan Mountcastle $5 and 2021 Topps Heritage Chrome Purple Refractors #185 Ryan Mountcastle/Bobby Dalbec $20.
I would need a little bit more to get to the autograph, but I would trade it straight up for the purple refractor and either of the other cards. Rizzo in it's condition books $25 graded. Unless you want some of the early 80's stuff to even it up for the Rizzo plus them for the lot.
MY feeling on the Rizzo BGS 7.5.
Typically I do more in PSA than any other grading platforms. What seems to be the norm is PSA 8 is usually equal to the raw value of the card. $25 for the card seems high. I am really trying to get my 1978 and 80's set needs finished and I would trade the Mountcastle cards to get them. I don't want to just make a trade without gaining on my needs. Let's hold for now unless you can meet more of my needs. Jim
