The Mayfower. The coins are quite beautiful ... BUT I couldn't help but notice that the U.S. commemorative $10 gold coin now weighs 1/4 of an ounce. Previously the $10 gold commemorative coins had weighed .483 of an ounce. Now they are little bigger than the $5 gold piece. Of course they had been made to the old standard, the issue price would have been well over $2,000.
