As a collector of United States Mint proof sets, I can confidently say that the 1991 set is a necessary addition to any collection. Not only does it contain beautifully crafted coins, but it also holds historical significance.
Firstly, the 1991 set includes all five denominations: penny, nickel, dime, quarter, and half dollar. This allows for a complete display of the different designs and compositions used in that year. As a collector, having a complete set is crucial for showcasing the evolution of coinage over time.
Moreover, the 1991 set marks an important transition in the design of US coins. It was the last year that the Lincoln Memorial design was used on the penny before being replaced by the iconic Lincoln portrait in 1992. The dime also saw a change in design with the introduction of the Roosevelt portrait on its obverse. These changes make the 1991 set a valuable piece for commemorating this significant shift in US coinage.
Additionally, proof sets are struck using special techniques that result in highly detailed and mirror-like finishes. This adds an extra layer of beauty and craftsmanship to each coin. The 1991 set is no exception and is a perfect representation of the high-quality standards maintained by the United States Mint.

My Buying Guide on ‘United States Mint Proof Set 1991’
I have been a collector of United States Mint Proof Sets for several years now and I must say that the 1991 set is one of my favorites. The set includes five coins, each struck with a special proof finish to showcase their intricate designs. If you are considering adding this set to your collection, here is my buying guide to help you make an informed decision.
What is a United States Mint Proof Set?
Before diving into the specifics of the 1991 set, it is important to understand what a United States Mint Proof Set actually is. These sets are specially made by the United States Mint for collectors and contain coins with a proof finish. A proof finish is achieved through a special minting process that gives the coins a mirror-like surface and sharp details.
The Coins Included in the 1991 Set
The 1991 set includes five coins: a Kennedy half dollar, Washington quarter, Roosevelt dime, Jefferson nickel, and Lincoln penny. Each coin is struck at the San Francisco Mint and bears the “S” mintmark. The half dollar, quarter, dime, and nickel are made of 90% silver while the penny is made of copper-plated zinc.
The Design
In my opinion, one of the highlights of this set is its design. The obverse of each coin features their respective iconic figures – Kennedy on the half dollar, Washington on the quarter, Roosevelt on the dime, Jefferson on the nickel, and Lincoln on the penny. The reverse designs also showcase important symbols and landmarks such as Monticello on the nickel and Independence Hall on the penny.
Packaging
The 1991 set comes in its original packaging from the United States Mint which includes a protective plastic case and a certificate of authenticity. This adds to its value as a collectible item.
Rarity and Value
The mintage for this particular set was relatively low compared to other years with only 2.8 million sets produced. This makes it more rare and potentially valuable for collectors. As with any collectible item though, it’s important to do your research and consider factors such as condition before determining its value.
Where to Buy
You can purchase this set from various sources such as coin dealers, online marketplaces like eBay or Amazon, or directly from the United States Mint website. However, I highly recommend buying from reputable dealers or directly from the Mint to ensure authenticity.
In Conclusion
The 1991 United States Mint Proof Set is definitely worth considering for any collector or even as a gift for someone interested in numismatics (coin collecting). Its beautiful design, rarity, and potential value make it a must-have in any collection. Just be sure to do your research before making your purchase!
