The 1966 Special Mint Set is a unique numismatic artifact produced during a national coin shortage when the U.S. Mint suspended traditional proof sets. These sets are highly collectible for their 'Special Mint Finish,' which offers a higher quality strike than circulation coins but remains distinct from standard proofs.
What Is 1966 United States Special Mint Set Worth?
The typical price range for 1966 United States Special Mint Set is $20 - $25 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:
- The physical condition of the original blue plastic housing and the outer white mailing envelope.
- The presence of 'Cameo' or 'Deep Cameo' contrasts on the coins, which are rare for this era and significantly increase value.
- Toning or spotting on the 40% silver half dollar, which can either enhance or detract from the set's market price.
- The overall clarity and lack of contact marks on the coin surfaces despite being uncirculated.
How to Identify 1966 United States Special Mint Set?
- Verify the presence of the 40% silver Kennedy Half Dollar, which is the only silver coin in the five-piece set.
- Check for the original government packaging, which consists of a flat blue plastic case held within a white envelope.
- Examine the coin surfaces for a satin-like luster that is more reflective than business strikes but lacks the mirror-like finish of a proof.
- Ensure all five denominations are present: Lincoln Cent, Jefferson Nickel, Roosevelt Dime, Washington Quarter, and Kennedy Half Dollar.
History of 1966 United States Special Mint Set
In 1965, the United States Mint ceased producing proof sets and regular uncirculated mint sets due to a national coin shortage. To bridge this gap, they introduced 'Special Mint Sets' from 1965 to 1967. These sets contained coins with a finish superior to standard circulation strikes but not as polished as traditional proof coins. The 1966 set is particularly notable as it contains the last 40% silver Kennedy Half Dollar issued for general collection in these sets, a short-lived vestige of silver coinage.
