The obverse of the coin depicts one of the geysers of the park. This is not identified as the famous "Old Faithful" since the landscape is different. The inscriptions include "Yellowstone", "In God We Trust", "Liberty", and the date of issue "1999". The coin’s reverse is adapted from the seal of the Department of the Interior. An American Bison is depicted facing left with the rising sun in the background. The inscriptions include "United States of America", "E Pluribus Unum", and the denomination “One Dollar”.
The Yellowstone Silver Dollars were produced at the Philadelphia Mint in proof and uncirculated formats. The coins were sold individually, or as a two coin set.
