Kennedy Half Dollars have been a staple of American coinage since their introduction in 1964. While many of these coins are common, certain error varieties have become highly sought after by collectors, with some fetching prices up to $6,000. This article delves into five notable error coins, providing detailed insights into their unique characteristics and current market values.
1. 1969-D Kennedy Half Dollar Struck on a Dime Planchet
One of the most intriguing errors occurs when a coin is struck on a planchet intended for a different denomination. In this case, a 1969-D Kennedy Half Dollar was mistakenly struck on a dime planchet.
Characteristics:
- Weight: Approximately 2.27 grams (standard dime weight)
- Diameter: 17.91 mm (dime size)
- Appearance: The design appears incomplete, with missing peripheral details due to the smaller planchet size.
Market Value:
Such errors are rare and can command prices ranging from $1,000 to $6,000, depending on condition and collector demand.
2. 1974-D Double Die Obverse (DDO) Kennedy Half Dollar
The Double Die Obverse error results from a misalignment during the hubbing process, causing a doubled image on the coin’s obverse.
Characteristics:
- Doubling Location: Prominent on the inscriptions “LIBERTY” and “IN GOD WE TRUST”
- Visual Cue: Clear doubling visible without magnification, especially on the letters.
Market Value:
In uncirculated condition, these coins can fetch between $50 and $1,000, with pristine examples reaching higher prices.
3. 1972-D Kennedy Half Dollar with Missing Clad Layer
This error occurs when one of the coin’s outer clad layers is missing, exposing the inner core.
Characteristics:
- Appearance: One side exhibits a copper-colored surface, indicating the absence of the nickel layer.
- Weight: Slightly lighter than the standard 11.34 grams.
Market Value:
Depending on the coin’s condition, these errors can range from $500 to $2,500.
4. 1964 Kennedy Half Dollar Accented Hair Variety
Although not a traditional error, the Accented Hair variety is a result of a design modification and is highly coveted by collectors.
Characteristics:
- Hair Detail: Enhanced hair strands above Kennedy’s ear.
- Reverse Marker: Missing serif on the “I” in “LIBERTY.”
Market Value:
Proof examples of this variety can command prices from $100 to over $4,000, depending on the grade.
5. 1971 Kennedy Half Dollar Struck on a Silver Planchet
In 1971, the U.S. Mint transitioned to a copper-nickel composition for half dollars. However, some coins were erroneously struck on leftover 40% silver planchets.
Characteristics:
- Weight: Approximately 11.5 grams (standard silver planchet weight)
- Edge: Distinct silver appearance without the copper core.
Market Value:
These rare errors can be valued between $2,000 and $6,000, contingent on condition and verification.
