I purchased two of these having read in Krauss that they were one-of-a-kind test-set cards. Krauss repeated that claim in last year's catalog update. However, I happened to check PSA population report last week and it listed 2 Mathewsons. I called to be sure it was not a misprint and the CS rep could not say one way or the other. I then called Al Rosen and he said that he does not believe that there are any cards of which only one copy was ever produced. He said they may have been new discoveries. Yesterday, I saw that there was a beat-up Mordecai Brown on Ebay and I find it hard to believe that is the only one of Brown.
