@heribase: Here’s where it gets interesting. A normal 1975 Roosevelt Dime can have no mint mark, so don’t assume every 1975 dime without an “S” is rare. The real treasure is the 1975 No-S Proof Roosevelt Dime. 🔎 What makes it special? Proof dimes from 1975 were supposed to carry the “S” mint mark from the San Francisco Mint. But on this extremely rare variety, the “S” is completely missing. And this isn’t just a normal no-mint-mark coin—it’s a genuine Proof variety with an extraordinary rarity. Only two examples are currently known. 💰 And the auction record is incredible: A 1975 No-S Proof Roosevelt Dime graded PCGS PR67 sold for an astonishing $506,250 at GreatCollections in 2024, setting the current auction record for this coin. ⚠️ Important: Finding a 1975 Roosevelt Dime without an “S” does NOT automatically mean you found the rare No-S Proof. You need to determine whether the coin is actually a Proof and matches the recognized characteristics. 📱 Have a 1975 Roosevelt Dime?
