Tips for Identifying Valuable Roosevelt Dime Errors

1. Inspect Mint Marks: Look for missing or repunched mint marks on 1982, 1968-S, and 1970-S dimes.
2. Search for Transitional Errors: Focus on 1965 dimes that may have been struck on 90% silver planchets.
3. Examine for Missing Layers: Missing clad layers expose the copper core and create visually striking errors.
4. Inspect Proof Coins: Limited mintage proof dimes, like the 1964-D and 1968-S, are highly collectible.
5. Grade Your Coins: Higher grades significantly enhance value. Consider professional grading through services like PCGS or NGC.
