There should be only one staple in a matchbook, Jim. Kind of looks like this is one of the 'reconstructed' matchbooks that we're starting to see on the market. A shiny staple or one that is too large is another clue to a cover that has been mated to matches to bring a higher price for the dealer. With feature matches, this kind of work can also create combinations of covers and matches that were never made by the match-maker.
