Hello! That's a great question about a classic American coin. The value of an 1890 Morgan silver dollar really depends on its condition, or what collectors call its "grade." A coin's value can range from its basic silver content to thousands of dollars for a pristine example.
First, every 1890 Morgan dollar contains about 0.7734 troy ounces of silver, giving it a base "melt value" of around $22.75. This is the absolute minimum it's worth. For a common, circulated coin that saw use as money, you can expect a value in the range of $35 to $60. This would apply to coins in "Good" to "Extremely Fine" condition, where the details are visible but there is clear evidence of wear.
The value starts to climb significantly for coins in "Uncirculated" or "Mint State" (MS) condition. These are coins that were never used and retain their original luster. A basic uncirculated 1890 Morgan from the Philadelphia mint (which has no mint mark) might be worth between $70 and $100. As the grade gets higher within the uncirculated scale, indicating fewer scratches and marks, the price can jump dramatically. A high-quality MS-65 example could be worth several hundred dollars.
It's also very important to check for a mint mark on the back of the coin, just below the eagle. The values mentioned are for the common Philadelphia issue, which has no mint mark. If you see a "CC" (Carson City), "O" (New Orleans), or "S" (San Francisco), the value will be different. The 1890-CC, in particular, is much rarer and more valuable. For an accurate assessment, especially if your coin looks to be in great shape, the best step is to have it examined by a reputable coin dealer.
