Section 1: The $6,995 Mystery – What Makes This Coin So Valuable?

Key Factor #1: The “S” Mint Mark (San Francisco Proof)
- Only 3,677,175 proof coins were minted in San Francisco in 1979.
- These were never meant for circulation—they were sold in special collector sets.
- Look for the tiny “S” below Susan B. Anthony’s neckline.
🔍 Interactive Check:
➤ Grab a magnifying glass and inspect your coin under bright light.
➤ No “S”? It’s likely a common Philadelphia (no mint mark) or Denver (“D”) coin.
Key Factor #2: Proof vs. Business Strike
Feature | Proof Coin (1979-S) | Business Strike (1979-P/D) |
---|---|---|
Finish | Mirror-like background, frosted details | Dull, matte finish |
Edges | Sharper, more defined | Slightly rounded |
Value Range | 300–300–6,995+ | 1–1–5 |
💡 Pro Tip: Tilt the coin under a light. If it reflects like a mirror, it might be a proof!

Key Factor #3: Condition & Grading
- PR-69 (Near Perfect): 300–300–500
- PR-70 (Flawless): 6,000–6,000–7,000+
🔹 Grading Trick: Use a 10x loupe to check for:
✔ No scratches, dings, or haze
✔ Full, crisp details on the eagle and lettering
Section 2: Beyond the “S” Mint – Rare Errors That Add Value
Even if your coin isn’t a 1979-S proof, these errors can make it valuable:
1. The 1979-P Wide Rim (Near Date) Variety
- Some Philadelphia coins have a wider rim, making the date appear closer to the edge.
- Worth 50–50–200+ in uncirculated condition.
2. Double Die Obverse (DDO)
- Look for doubled lettering on “LIBERTY” or the date.
- Can sell for 100–100–1,000+ depending on severity.
3. Off-Center Strikes
- If the design is misaligned, it could be worth 20–20–500+.

Section 3: How to Verify & Sell Your Coin
Step 1: Get It Graded
- PCGS or NGC certification is a must for high-value coins.
- Cost: ~30–30–50 (worth it if your coin grades PR-70).
Step 2: Where to Sell
- eBay (for raw coins) – List with clear, high-res photos.
- Heritage Auctions (for certified coins) – Best for premium pieces.
- Local Coin Shows – Negotiate with dealers in person.
Step 3: Avoid Common Scams
❌ Don’t accept “quick cash” offers from pawn shops.
✅ Always research recent sold listings before pricing your coin.
Final Checklist: Is Your Coin Worth $6,995?
✅ It has an “S” mint mark.
✅ It has a mirror-like proof finish.
✅ It’s in flawless condition (no scratches, wear, or haze).
