There are coins in there...but took me a while to open it because I first needed to show it to everyone I know lol!
That's a good one! I occasionally get coins mailed to me using vintage stamps like that (but not that cool). The current state of stamp collecting is most are worth face value.
This is why I don't sell on Ebay. I think they eventually get to the destination but long after a case is opened and refund is issued.
