The Goloid metric dollar was minted by the U.S. Mint in Philadelphia as a pattern coin, but it was not a typical silver dollar. Goloid was an alloy that consisted of gold, silver and copper. The pattern coins were produced with varying amounts of gold and silver in the coins and the alloy was patented by Dr. William Wheeler Hubbell of Philadelphia. The idea was to replace all our silver coinage with goloid coins. But for various reasons, the goloid coins were never approved and the idea was dropped.

The 1879 $10 gold piece was minted at 4 different mints. The mintmark is a small letter located on the reverse [tails] side of the coin just under the eagle. There should be a "D", a "CC", an "O" or none at all. If there is no mintmark at all then that means the coin was minted at Philadelphia. Locate the mintmark and then resubmit your question and an approximate value can be determined.
