You say "we will never be able to prove 100% either way (if the Piedmonts are period or printed later)". Based on what I've learned on this thread, it would seem that microscopic analysis of the dot matrix pattern would conclusively determine whether the card is period. If it matches up against other known period Piedmonts, than for all practical purposes the card is real. To quote David Cycleback, who makes the point real well, "at a time when a T206 Eddie Plank was worth $3 and Allen & Ginter Cap Anson 30 cents, setting up a chemistry lab to recreate 1909 paper and ink seems far fetched". Now all we have to do is get the new owner of the card to submit it for microscopic analysis and we can resolve this case!
