Morgan Silver Dollars
Morgan Silver Dollars aren't very uncommon in and of themselves, but some of the most rare vintages may command astronomical sums. Even if you don't have one of the more unusual varieties, the Morgan is a lovely coin with the substantial feel of a well-balanced, 90% silver coin.
Its silver content and the current price of the precious metal, Morgan should bring at least $20. The following Morgan examples, on the other hand, can bring in a lot more, but pay attention to the mint mark, which is an alphabetical designation on some coins.
According to CoinTrackers, each of them might fetch anywhere from $100,000 to $550,000 if it's in pristine condition. There are even more variations of the Morgan silver dollar that may fetch tens of thousands of dollars.
Price: at least $10
