1. Morgan Silver Dollar (1878-1904, 1921): Well-preserved Morgan silver dollars in circulated condition can range in value from around $30 to several hundred dollars, depending on the specific year, mintmark, and overall condition. However, some rare Morgan dollars, such as certain low-mintage years or special commemorative issues, can command much higher prices and may be worth thousands of dollars or more.
2. Peace Silver Dollar (1921-1935): Peace silver dollars in circulated condition may have a value ranging from approximately $30 to a few hundred dollars, similar to Morgan dollars. The value largely depends on the specific year, mintmark, rarity, and condition of the coin. Higher-grade specimens or rarer date/mint combinations can be significantly more valuable, with some commanding premiums in the collectors' market.
3. Eisenhower Silver Dollar (1971-1978): Eisenhower silver dollars are relatively modern compared to Morgan or Peace dollars, but as they approach the 100-year mark, some earlier issues (especially proofs or coins in particularly good condition) may show some appreciation in value over time. Generally, circulated Eisenhower dollars are valued in the range of $10 to a few dozen dollars based on condition and scarcity within the series.
To determine the exact value of your specific 100-year-old silver dollar coin, it's recommended to have it professionally appraised or researched by consulting reputable coin dealers, online resources, or numismatic reference materials. The coin's history, mint state, scarcity, and overall numismatic significance all play a role in determining its worth.
