Weighing The Half Dollar
Coin collectors and history buffs alike often marvel at the U.S. half dollar coin. With its unique denomination and rich history, understanding the half dollar’s weight can reveal insights into its composition and evolution. This section delves into the specifics, exploring how much a half dollar weighs and uncovering the story its weight tells.
Standard Specifications
The half dollar, a mainstay in American pockets and collection displays, holds a standard weight specification that has been relatively consistent across modern issues. Notably, the John F. Kennedy half dollar—introduced in 1964 and still minted today—has maintained a weight that collectors have come to expect.
- Material: Cupro-Nickel Clad
- Diameter: 30.61 mm
- Weight: 11.34 grams
Earlier half dollars, like the Franklin and Walking Liberty, match these specifications.
Variances Over Time
Throughout history, the half dollar has seen changes in weight. These variances reflect adjustments in metal composition, influenced by economics and legislation.
Period | Coin Type | Weight |
---|---|---|
1794-1836 | Early Half Dollars | 13.48 grams |
1836-1964 | Silver Half Dollars | 12.50 grams |
1965-present | Cupro-Nickel Clad | 11.34 grams |
It’s important to note that silver half dollars are heavier due to their 90% silver content. Post-1964, the weight decreased as coins transitioned to a copper-nickel composition. This shift marked a significant change in the half dollar’s weight and historic journey.
The Impact Of Metal Composition
The impact of metal composition on a coin’s weight is significant. Each half dollar, depending on its year of minting, consists of different metals which influence its mass. Let’s dive into how the metal composition affects the weight of these unique coins.
Silver Content In Older Half Dollars
Older half dollars are famous among collectors. Not just for their design, but for their silver content.
Year | Composition | Weight |
---|---|---|
Pre-1965 | 90% Silver, 10% Copper | 12.5 grams |
1965-1970 | 40% Silver, 60% Copper | 11.5 grams |
Notably, these older coins with higher silver content weigh more than their later counterparts.
Modern Clad Coinage
In contrast, modern half dollars are made through a method called cladding.
- Outer layers are 75% copper and 25% nickel.
- The core is pure copper.
These changes lead to a standard weight of 11.34 grams for half dollars minted after 1971.
