I was cleaning my basement and ran across these in an old box. Do any of you coin and medals gurus know anything about these? Are they of interest to anyone? Do they have any value?

The first is a medal from the 1962 Seattle World's Fair. The reverse says it is good for $1 at the Century 21 exposition grounds.

The second commemorates the grand opening of BART in the bay area in September 1973.

The third commemorates the coronation of King George VI and Queen Elizabeth on May 12, 1937. Any help from the English Chip Guide Community? I guess I picked it up at an outdoor market around 1970.

The last is a sealed 1921 silver dollar. It looks like it's in terrific condition, possibly uncirculated, but what do I know? Very little about coins.

I appreciate any help. Feel free to respond on the board or by e-mail.
