Here's some shocking (or maybe not shocking) news: you will never find a 1975 quarter in pocket change because they don't exist. The quarters that were made in 1975 are dated 1976. Those were minted in 1975 and 1976 because the mint wanted lots of them. But the 1976 dated quarters didn't begin production until July 4th, 1975, so couldn't the mint just make the 1975 dated quarters earlier in the year? It's not that easy.

Benjamin Franklin Half Dollars were struck from 1948-1963. It was the last full coin design change before the ones we are familiar with today. It was struck in 90% silver. This was the fifth coin with an actual person, and the first with a person who had not held office as a president. The obverse has a bust of Mr. Franklin, one of the most liked, and in my opinion, interesting founding fathers to this day. The reverse of this particular 50 cent piece has the Liberty Bell in all of it's cracked glory, along with a tiny Eagle, which is the smallest of our national animal ever depicted on a coin. The Ben Franklin Half Dollar has a reeded edge. The circulation strikes were struck at the San Francisco mint, along with the Philadelphia and Denver mints. The proofs were made by the Philadelphia mint, in addition to the circulation coins.

The US realized their mistake around 1952, and requested the coin back. But World War II happened, and the return was delayed. Then, many of King Farouk's coins were auctioned off, one of which was the 33' double eagle. The US asked once again for the coin, and authorities in Egypt said they would comply, but the coin vanished. Until 1996.
