I know there are several collectors out there who collect certain back stamps (ex. Lloyd Bolton, Howe McCormick, Big Purple numbers, etc.). I was thinking why a current collector doesn't do the same?; Stamp or mark each card in their collection in a unique way. No doubt it would diminish the value today, but they might be comforted by the fact that some collector not yet born might hunt down "their" collection someday.

What do you think? Is this a neat idea, or blasphemy and deprecation?
