Trade Dollars "authenticity unverifiable"
I sent three Trade Dollars in for grading. All three were cleaned when I got them from a friend 20 years ago. Because of counterfeit Trade Dollars floating around I at least wanted to have them as "Genuine" cleaned. One came back "Genuine" cleaned and two came back "authenticty unverifiable". I am including photos. PCGS said the graders don't share notes about what they observe. Just wondering the difference between "authenticty unverifiable" and counterfeit.
