Collecting quarters minted after 1965 can be a rewarding endeavor, especially when certain rare specimens are valued at over $10,000. These modern rarities often owe their worth to unique errors, limited production, or exceptional preservation. Below is a detailed exploration of the top seven quarters from this era that have commanded impressive prices among collectors.
1. 1965 Silver Washington Quarter Error
In 1965, the U.S. Mint transitioned from 90% silver quarters to a copper-nickel clad composition. However, a few quarters were mistakenly struck on leftover silver planchets from 1964, resulting in a rare error coin.
- Notable Sale: One such error coin fetched approximately $7,000 to $10,000, depending on its condition.
2. 1970-S Proof Washington Quarter (Struck on 1941 Canadian Quarter)
A remarkable minting error occurred when a 1970-S proof quarter was struck on a 1941 Canadian quarter, leading to a thinner coin with unique markings.
- Notable Sale: This extraordinary error coin sold for over $35,000 at auction.
3. 1967 Special Mint Set (SMS) Washington Quarter
During 1965 to 1967, the U.S. Mint produced Special Mint Sets instead of regular proof sets. The 1967 SMS quarter, especially in pristine condition, is highly sought after.
- Notable Sale: A 1967 SMS Washington Quarter achieved a price of approximately $17,000.
4. 1982 Washington Quarter
Due to the economic recession in the early 1980s, the U.S. Mint did not produce traditional Mint Sets in 1982 and 1983, making high-quality quarters from these years scarce.
- Notable Sale: An exceptional 1982 Washington Quarter sold for around $8,500.
5. 1966 Washington Quarter
Although over 800 million quarters were minted in 1966, finding one in Mint State (MS67) condition is rare.
- Notable Sale: A 1966 Washington Quarter in MS67 condition fetched approximately $8,000.
6. 1965 Washington Quarter (MS67+ Grade)
In the first year of clad composition quarters, 1965, specimens in exceptional grades are highly valued.
- Notable Sale: A 1965 Washington Quarter graded MS67+ sold for about $12,000.
7. 1971-S Washington Quarter
The 1971-S proof quarter, especially in PR68 Deep Cameo or higher grades, is considered valuable.
- Notable Sale: A 1971-S Washington Quarter achieved a price of approximately $3,500.
