Does anyone know (amybe I just missed the boar somewhere) how to be able to detect watermarks on a stamps that is still on the postcard (first one that says take it off the postcards gets it!). I can figure years of use approximately, perforations and the rest but not the postmark and with some of my older US stuff that is kind of important. All opinions welcome - thanks in advance - Jeff
HI Nigel, I have some of those and they work sort of ok, but I dont think they will detect on postcard of through post card, but I will try it when I get home, thanks for the tip - Jeff (will let you know)
I've had some success with the Roll-a-tector detecting watermarks on US stamps on cover but don't recall using it for a stamp on a post card. In theory it should work on post cards as well.
