Prices for United States Coins: Note: The prices listed below are for the most common dates of U.S. coins in average circulated or typical uncirculated condition. Coin prices may or may not be currently accurate but are intended to show relative value. Coin values depend upon condition and rarity. Here are the top 25 most valuable silver dollars (Morgan's/Peace Dollars) from the late 1800's to the early 1900's (updated: 2020). We've searched through the coin catalogues, books, and online stores and made a huge list of coin values. We then filtered the data to show only the most expensive silver dollars, and this is what we came up with.
