Tips for Finding Valuable

1. Inspect Mint Marks: Check for missing or repunched mint marks, particularly on 1982, 1968-S, and 1970-S dimes.
2. Look for Transitional Errors: Pay attention to 1965 dimes that may have been struck on silver planchets.
3. Examine for Missing Layers: Missing clad layer errors often reveal a copper core.
4. Search Proof Coins: Proof dimes from limited mintage years like 1964-D and 1968-S are highly collectible.
5. Grade Your Coins: Higher grades significantly boost value. Professional grading services like PCGS or NGC can authenticate and appraise your coins.
