JFK half-dollar
Everyone seems to have forgotten the Eisenhour half-dollar, which had a bust of that President on one side and I forget what on the other (I have one at home). After the release of the Kennedy half-dollar, you didn't see them any more, and the Kennedy half-dollar was as short-lived as all half dollars. I hasn't been a popular coin because of its size.
No one has mentioned the gold coins, which were not uncommon before the U.S. went off the gold standard in the 1930's. (My father mentioned that his parents received their pay weekly, in gold and silver, no notes). The eagle was a gold coin about the size of a quarter, featuring an eagle, and worth $10; the half-eagle ($5) was smaller; the double eagle ($20) was about the size of a half dollar and was a very handsome coin. There were also bank notes which were redeemable in gold.
