They can be worth quite a bit! Particularly if they’re some of the earlier types like Flowing Hair Silver Dollars, Seated Silver Dollars, and Trade Silver Dollars. There are even proof silver dollars. These are silver dollars with very low mintages (less than 1,000). As a result, they’re in high demand among serious coin collectors (us included!).
At minimum, even a heavily worn silver dollar is worth a bit more than its melt value, but can go much higher. We have bought and sold individual silver dollars for more than $70,000. It all depends on its rarity and condition.
See our Carson City Silver Dollar Price Guide for more information on those Morgan silver dollars.
