The gold $1 coin was minted from 1849 to 1889. There were three types over its lifetime and all of them were designed by Mint Chief Engraver James B. Longacre. The large supply of gold bullion that resulted from the California gold rush prompted Congress to authorize minting of the coin. The Type 1 issue has the smallest diameter of any United States gold coin minted to date. There was quite a bit of oppostion to the small size of the coin, but some regarded it as a very beautiful and delicate coin. A nice addition to any gold type coin collection. This is a great place to find a nice variety of these gold coins.
