I first noticed clipped coins when a collector showed me a George Washington quarter with suspiciously smooth edges. The damaged coin sparked my curiosity - why would anyone alter currency this way? Let's explore the legal and historical aspects of coin mutilation.

Coin clipping refers to illegally shaving precious metals from coin edges. In the United States, Title 18 Section 331 of U.S. Code explicitly prohibits defacing coins with penalties up to $10,000 fine and 5 years imprisonment.

This practice isn't just modern vandalism. Let me walk you through its surprisingly royal origins and why those ridges on your coins matter more than you think.

Why is coin clipping¹ bad?

Coin clipping destroys historical value and economic trust. When I inspected a 1792 half disme for a client, the missing silver content from edge shaving reduced its value by 87%.

Clipping coins reduces metal content, destabilizes currency systems, and enables counterfeiting. Modern reeded edges² act as both security feature and historical safeguard against precious metal theft.

3 key impacts of coin clipping:

1. Economic Impact
   Reduces actual value vs face value
2. 콜렉터 임팩트
   Makes authentication difficult
3. Legal Impact
   Triggers felony charges in most countries

Who invented coin edges?

The solution came from England's Royal Mint. While examining Isaac Newton's mint records (yes, that Newton), I discovered his 1696 memo about "ridged crowns to foil clippers."

Sir Isaac Newton introduced reeded edges as Master of the Mint in 1696. This innovation combined security and practicality - ridges made clipping detectable while improving coin stacking.

Edge evolution timeline:

• Ancient Coins (pre-1500): Plain edges
• Spanish Milled Dollars (1732): Crude markings
• Newton's Great Recoinage (1696): Standardized reeding
• Modern Security Edges (2000s): Laser-engraved patterns

What does the D stand for on a penny?

The mint mark mystery unraveled during my visit to Denver Mint. That tiny "D" represents more than location - it's quality assurance in miniature.

The D on pennies indicates Denver Mint production. Since 1906, this mark guarantees specific silver content ratios and minting standards unique to this facility.

How to tell if a coin is uncirculated?

Last month, a client nearly bought a "mint condition" 1921 Morgan dollar until we spotted micro-scratches. Here's how to avoid such mistakes.

Uncirculated coins show zero wear marks, full mint luster, and sharp edge details. Use 10x magnification to check for bag marks or contact scratches.
