Up for sale is a America's Changing Washington Quarter four coin set from The Morgan Mint.  This set is sealed in hard plastic and contains four Washington quarters.  There is a 1976 Bicentennial quarter (can't find the mint mark), a 1998-P, 1999-P Pennsylvania state quarter, and 1999-P Delaware state quarter.  Coins are very clean, but I would guess at least the 1976 coin is circulated.  Case has some scratches and wear, but displays very nicely.  Great addition to any collection.  Thanks for looking!
