This specific item ID of the WoW Token is what players receive from purchasing the token from the Auction House.  It may not be traded or re-sold, nor (at this time) may it be stored in your bank.  Also, there appears to be a one minute cooldown period between searches for WoW tokens.  If you are making a purchase of a token but the token is bought out before your own transaction is complete, the gold will be refunded in a letter sent to your mailbox (see screenshot).
