Hello there! That's a great question. The 1900 Morgan Silver Dollar is a fascinating coin, and its value can really vary quite a bit depending on a few key factors.
The most important things to look at are its condition, or grade, and where it was minted. In 1900, these dollars were produced at three different U.S. Mints: Philadelphia, New Orleans, and San Francisco. To find the mint mark, you'll want to look on the reverse (tail's side) of the coin, just below the eagle's tail feathers. If there is no mint mark, it was made in Philadelphia. If you see a small "O" it's from New Orleans, and an "S" means San Francisco.
Coins from the Philadelphia (no mark) and New Orleans (O) mints are very common for that year. If your coin is in average circulated condition, meaning it shows wear from being used as money, its value is often tied closely to its silver content, which is about 0.7734 troy ounces. In uncirculated, or "Mint State," condition, these coins can be worth significantly more, starting around $50 to $65 and climbing much higher for top-grade examples.
The 1900-S Morgan Dollar from the San Francisco mint is the scarcer of the three and generally carries a higher value. Even in circulated condition, it's typically worth more than its counterparts from the other mints. If you have a 1900-S in uncirculated condition, it could be quite valuable.
So, to figure out what yours is worth, first check for that tiny "O" or "S" mint mark on the back. Then, take a close look at its condition. A heavily worn coin will be valued near its silver price, while one that looks brand new with sharp details will command a much higher premium, especially if it's a 1900-S.
