I just was checking out Ebay. some guy had a 1980 Susan B Anthony souviner PDS set sealed in its original envolope. Below the pic. of the envolope there was three SBA. I asked him if the coins pictured below were the coins that would be sent. He sent back a ''Yes''. How can that be if the envolope is sealed?
He probably means that the cellophane is still sealed. I don't think the envelope on those sets were sealed.
