So how do you suggest I prove authenticity ? I ' m not sure what else I can do aside from post the conversation I had with the support . <| sep |> Ja du snakker og din kft den lugter <| sep |> I use bullion as a catch all term to refer to everything made of silver that does not have an exceptional collector value attached to it . Back in the real old days coin collecting with the blue books , you could purchase some special production coins directly from the mint that were either proof or uncirculated . You also could get the same coins as the uncirculated from the bank , but those were used for everyday commerce , hence circulated . Proofs were what they are today , highly polished examples of those same coins . IMHO , brilliant uncirculated isn ' t much more than a marketing term any longer . To me all it means is the coin is new and has not been damaged or corroded .
