What’s the Buzz About the Bicentennial Drummer Quarter Error?
Lately, more and more collectors — and even casual coin hunters — are finding the famous Bicentennial “Drummer Boy” Quarter Error.
You’ve probably seen this quarter before — it’s the one with the drummer design on the back and dates 1776–1976 on the front. 
But here’s the secret: some of these coins hide a valuable minting error that could make them worth hundreds of dollars! 
What to Look For on the Bicentennial Quarter
Here’s what the video (and your Coin Teacher) shows in detail:
Mint Mark:
- Look for the “D” mint mark under the date — this means it was made in Denver.
The Doubling Error:
- Under magnification, check for doubling in the inscriptions:
- LIBERTY
- IN GOD WE TRUST
- You’ll notice extra lines or shadows around some letters — especially the R and T.
Comparison Helps:
- A normal coin will have crisp, single lines with no extra marks.
- The error coin shows distinct double lines, especially around the top lettering.
How Much Are These Error Quarters Worth?
If you find one of these Denver-minted Bicentennial Drummer Quarters with visible doubling:
- Average condition: $200+
- High-grade (uncirculated or proof-like): Up to $800 or more!
That’s a lot for a coin that could be sitting in your change jar right now!
