Technical Specifications of the US Quarter
The standard US quarter, also cognize as the Washington Quarter, has undergo specific metallurgical modification over the ten. Since 1965, the composition of the coin transfer from silver to a cupro-nickel clad design to see durability and lower production costs. Realise these component is essential for accurate calculation.
Current Composition and Mass
- Weight: 5.670 gram.
- Diameter: 24.26 millimeter.
- Thickness: 1.75 mm.
- Composition: Outer level of 75 % cu and 25 % nickel, stick to a staring copper core.

| Number of Fourth | Full Weight (grams) | Total Value (USD) |
|---|---|---|
| 1 | 5.67 | $ 0.25 |
| 10 | 56.7 | $ 2.50 |
| 40 | 226.8 | $ 10.00 |

- Dirt and Grime: Accumulated crude, dirt, or oxidation on the surface of the coin can add a small fraction of a gramme to the total muckle.
- Strike Variations: While rare, tenuous deviation in the pressing or metal white preparation can leave to super minor divergence that are usually only noticeable by professional numismatists.
Historical Context: The Silver Era
Before 1965, quarters were coin with 90 % ag and 10 % bull. These coins are significantly different in density and raft equate to modern cupro-nickel variants. A pre-1965 ag quarter weigh roughly 6.25 gramme. Collectors oftentimes keep these coins differentiate from modernistic modification because their bullion value far exceeds their aspect value.
