The first Peace dollars were struck in the final week of 1921 exclusively by the principal mint. The beautiful high-relief engraving caused issues with production, slowing the minting process. Just over one million were output, which was a fraction of the number struck the following year. Today it's estimated that less than 45,000 survive in mint-state condition, which makes these About Uncirculated specimens a great option for collectors. AU coins have very light wear and still possess original luster.
