I was able to UpGrade my PSA 3 (mk) Center Fielder to a PSA 5!
The PSA 3(mk)Card has what appears to be a Catalog stamped Number(950)
on the Back Top Left side... it's somewhat faint.
I have many Cards to Trade for the PSA 4.5 PITCHER,
or Any One of the 1st or 2nd Base PSA High Grades.
I also have a few nice E90-1's to Trade...
"Thanks iN AdVance!" for Helping out an Ole' Sailor... Any way possible ~
My Claim to fame. This is the only Set that I actually put together and even thats debatable!?
However, i have been working on the E90-1 Set Since 2011
I do have about 95% of the HOFer's and Tuffies out of the Way...
Got that goin fir me!
