If you’ve ever seen or owned an older $20 bill, you’ll want to save this guide.
Some of these notes can be worth hundreds of dollars — and the secret lies in spotting rare printing errors that most people overlook.
Here’s how to identify some of the most valuable examples.
🔥 3 Valuable $20 Bill Printing Errors
1️⃣ Gutter Fold Error — Value: ~$138
At first glance, this printing mistake can look like damage — but it’s actually a fold in the paper during printing.
The ink skips where the fold was, creating a blank, streak-like area.
- Common on older notes, but still valuable to collectors
- This example recently sold for $138
2️⃣ Misplaced Black Seal — Value: ~$140
Look at the black Treasury seal on the left side of the front of the bill.
- If it’s not in the correct spot, the bill is considered a misalignment error
- Even with the rest of the design perfectly normal, one mispositioned seal brought in $140
3️⃣ Missing Front Seal (Overprint Error) — Value: ~$600
This is a big one. On some older $20s, the seal on the front is completely missing — but the back still shows the correct serial number and seals.
- Known as an overprint error
- One such example sold for $600
🔍 Why These Errors Are Valuable
- Printing errors are rare — especially on older currency
- Collectors love unique, visually obvious mistakes
- Even circulated notes can bring in strong prices
📌 Tips for Spotting & Handling Error Bills
- Inspect both sides — look for missing or misplaced elements
- Check the seals & serial numbers for alignment issues
- Do NOT fold or damage the bill — keep it flat in a protective sleeve
- Get an expert opinion from a currency dealer or grading service
📢 Final Word
Older $20 bills can hold hidden value far beyond their face amount.
A gutter fold, misplaced seal, or missing seal could turn your $20 into $600 — or more.
