Gilbert MainesYou may be able to locate persons who value printing errors more highly than most collectors. I have seen a few that were rather attractive curiousities. Locating persons potentially interested in your card may be best accomplished by listing it on eBay. Put what you consider to be a high reserve on the listing, and if someone buys it you are lucky; if no one reaches the reserve, then you have an idea of what price the current market will support.
Please come back if you include prewar cards in your interests. And maybe even if you don't yet.
