- Mint State (MS): Uncirculated coins are graded on a scale from MS-60 to MS-70, with MS-70 being the highest grade. The closer a coin is to MS-70, the more valuable it will be.
- Rarity: The 1879 silver dollar is a relatively common coin, but there are some key dates and varieties that can be quite rare and valuable. For example, the 1879-S silver dollar (minted in San Francisco) is much rarer than the 1879-P (minted in Philadelphia).
- Condition: The overall condition of the coin is also important. Factors such as scratches, nicks, and toning can all affect the value of the coin.
- Eye appeal: Some coins may have certain characteristics that make them more appealing to collectors, such as a particularly attractive toning pattern or a strong strike. These coins may command a higher price.
Overall, an 1879 silver dollar in uncirculated condition can be a valuable coin, but the exact value will depend on a number of factors. If you have an 1879 silver dollar and are interested in knowing its value, it's best to have it professionally appraised by a coin dealer or numismatist.
