March 16, 2026Understanding the 40% Kennedy Half Dollar for Jewelry Crafting
Not every coin is suitable for crafting. Let me walk you through the metal composition and durability of this piece for jewelry making, particularly when considering it for coin rings and other wearable art.
Metal Composition and Silver Content
The 1965-1970 Kennedy half dollars contain 40% silver, making them a popular choice for crafters. This composition consists of:
- 80% copper core
- 20% silver outer layer (40% total silver content)
- Clad construction with copper-nickel outer layer
For jewelry making, this 40% silver content provides a good balance between workability and value. The copper core gives the coin more structural integrity than pure silver, while still offering that desirable silver appearance once finished.
Metal Hardness and Workability
The 40% silver composition offers moderate hardness, making it more forgiving than 90% silver coins when being shaped into rings. Here’s what you need to know about working with this alloy:
The copper core provides better resistance to bending and cracking compared to higher-purity silver coins, which is crucial when stretching or folding the coin to create a ring.
The metal responds well to annealing (heating to soften), allowing crafters to repeatedly shape the coin without excessive risk of cracking. This makes it ideal for beginners learning coin ring techniques.
Design Details and Aesthetic Appeal
The Kennedy half dollar features President John F. Kennedy’s profile on the obverse, designed by Gilroy Roberts. The reverse shows the presidential seal with the eagle, created by Frank Gasparro. These design elements offer several advantages for jewelry crafting:
- The detailed profile creates visual interest when the coin is shaped into a ring
- The eagle design on the reverse can become a striking centerpiece in certain ring styles
- The reeded edge adds texture and authenticity to finished pieces
The 30.6mm diameter provides ample surface area for creating men’s rings (typically size 10-13 when made from a half dollar) or wider women’s bands.
Historical Significance and Collector Value
Minted from 1965-1970, these coins were created as a compromise during the silver shortage. Understanding their history adds value to your crafted pieces:
These coins represent a transitional period in American coinage, bridging the gap between 90% silver circulation and the clad coinage we use today.
When crafting with these coins, you’re working with pieces that hold both intrinsic silver value and historical significance, which can be highlighted in your finished jewelry.
Practical Considerations for Crafters
Before working with 40% Kennedy half dollars, consider these practical aspects:

Conclusion: The Crafter’s Perspective
