I have a few questions for the casino playing card collectors. Is the value of a pack of cards affected by the pack being opened. If so, which is more desirable? If the pack is devalued by being opened or sealed, by how much (as a rule, I know it must vary)? I have some decks which I have left sealed, but would be interested in seeing if they have any unusual cards or designs on any or all of the cards. Any suggestions are welcomed.
