1. Condition:** The condition of the coin greatly influences its value. Here are the approximate values for different conditions:
- Good (G): $50 - $100
- Fine (F): $150 - $200
- Very Fine (VF): $300 - $400
- Extremely Fine (XF): $500 - $750
- Uncirculated (UNC): $1,000 - $3,000
2. Mint Mark: The value can vary depending on the mint mark. Philadelphia coins (no mint mark) are the most common and therefore less valuable. Coins minted in Carson City (CC), San Francisco (S), and New Orleans (O) may have a higher value due to their relative scarcity.
3. Rarity: Some 1880 American eagle silver dollars may have special characteristics or errors that make them even rarer and more valuable. These include things like die cracks, doubled dies, or off-center strikes.
It's important to note that coin values can change over time due to market fluctuations and various factors affecting supply and demand. Consulting a reputable coin dealer or numismatic expert for an accurate appraisal of your specific American eagle 1880 silver dollar is recommended.
