I need some recommendations on where to send pieces for authentications. I have collected for about twenty years but only after this past summer got into the I.D. and authentication stuff. I have way to many to do I would like to have some of the tools done. I see all kinds of coa's and they seam to charge about the same. Just looking for opinions from you guys that are more knowledgeable about that kind of stuff.
