      Proof Sets

      The US Mint first produced proof coins in the 1800s. Proof coins were special coins manufactured with an extra-fine finish on the surface, after which they were sold to coin collectors via the US Mint offices. However, every coin in circulation does not have a proof counterpart, which is one of the reasons why they are a collector’s item.

      As time passed, coin collectors started to demand a proof coin for every type of coin that was minted. Later in 1936, the United States mint began producing coin sets for every coin minted, and those were sold directly to collectors. These coins could also be ordered through the mail.

      Later on, the US mint also started producing commemorative coins. The US mint was producing these coins in proof and business strike finishes. There were produced in varying sets that combined coins of various denominations and finishes; these were also sold to collectors. In the present-day United States, anyone can order proof coins directly from the United States Mint website. The process is quick and easy for the most part.

      Proof Coins – Rarities, Varieties, and Special Dates

      Now, if you have a few proof sets and want to get a quick idea of what it is worth, then you should find the after-mentioned section useful. We have covered proof sets that tend to be worth a lot of money regardless of their condition. That’s why these coins are so commonly counterfeited, or common coins are altered to look this way. For this reason, before you start opening up that vintage wine bottle and planning for early retirement, get the coins authenticated by our team.

      Below is by no means a comprehensive list, but it should be a good start.

      • Proof sets from 1936 – 1951. Generally speaking, we’d say you should be careful when buying these sets. These were not packaged like the proof sets sold today, with hard plastic cases. These proof sets were shipped in cellophane or paper envelopes. So, it is fair to assume that the acids in the metals have reacted with the coins causing damage. That’s why we don’t expect them to be in perfect condition.

      • 1971-S No S Jefferson 5-cent. The so-called Jefferson nickel does not have the “S” mintmark on its obverse.

      • 1990-S No S Lincoln cent. This one, too, is missing the “S” on the observe which should be under the date.

      • 1981-S Clear S. The mintmarks on all these coins are flat and clear

      United States Mint Commemorative Coins

      Commemorative coins were officially launched in 1892 by the United States Mint. However, 44 years, prior a special “one-of-a-kind” coin was produced in 1848, which was made from the newly discovered gold in California. It was August of 1848 when a special shipment of over 14 pounds of gold was sent to the US mint in Philadelphia, which was to be refined to determine its purity and confirm if it was, in fact, gold discovery in the west. Soon after testing, the majority of this so-called first gold was then used to make 1389 $2/1/2 Gold Quarter Eagles in 1848, to serve as commemorative coins, and celebrate the discovery of gold. The “CAL” stamped gold coins were the first ones to be issued by the US mint, which makes them so rare and valuable.

      It wasn’t until much later, in 1892, that the first official commemorative coinage had started being produced. The first ones produced were for the World’s Columbian Exposition with the Columbian Half-Dollar, mainly serving as a commemoration to the 400th year of Columbus’ discovery of the Americas. The very next year, the Columbian Exposition quarter dollar with Queen Isabella of Spain on its face was issued.

      Early Commemoratives Collections

      The US gold and silver issues are either collected by their types or their sets based on mintmarks. Many people find these coins fun to own because they tell a part of history that isn’t taught in regular history books. However, for the investor/collector, these coins appreciate in value far beyond their face value. Some of the most popular and rare US commemorative coins which include but aren’t limited to:

      • World’s Columbian Exposition Isabella Quarter which was produced from 1892 to 1893

      • World’s Columbian Exposition Half Dollar, which was produced from 1892 to 1893.

      • Lewis and Clack Exposition, which was produced between 1904 and 1905

      • The Lafayette Dollar was produced in 1900

      • Panama-Pacific Exposition, which was produced in 1915

      • The Louisiana Purchase Exposition which was produced in 1903

      The Latest Commemorative Coins

      The commemorative coin program had been halted for a few decades until it was restarted in 1982, which re-invigorated the Numismatics. The first coin to be produced was the Washington commemorative half dollar coin, which marked the 250th anniversary of the capital’s birth. Since then, the US mint has produced many excellent coins to commemorate various events or places. Today there are many different varieties that will thrill just about any collector, seller, or buyer in the market for them.

      If anything, each commemorative coin is made with the idea that it is part of American history. So, not only do these coins represent an investment in the country’s past but ensuring its future. Furthermore, commemorative coins produced by US Mints are a way for the country to raise money for causes while commemorating significant points in the Republic’s history. Not only are they a beautiful addition to your collection, but they capture money art in the best way it can be captured.

      Commemorative Coin Collections

      There is so much right now being talked about and written about when it comes to US commemorative coins that covering every aspect of each collection is hard to do in a single article. However, generally speaking, military-themed commemorative coins with patriotic and Boy Scouts themes are very popular commemorative coins.

      Also popular are coins with sports themes like Olympic events, the Baseball Hall of Fame, and other commemorative coins. Furthermore, commemorative coins mark emotional issues like those associated with Civil Rights, Breast Cancer Awareness and March of Dimes, etc. Regardless of what may interest you, we are pretty sure that there is a coin out there for you to collect that commemorates it.

      As a commemorative coin collector, it is also important to be aware that these coins are available in varying finishes like proof and uncirculated. They are made from different types of metals like silver, clad, or gold, with prices ranging from $25 on the low end to $250 and sometime much more. The worth of these coins tends to vary, so it’s hard to know the value without examining the coin or knowing more about it. Furthermore, some collectors choose to collect coins with a particular type of finish only. Advanced collectors opt to collect all variations with different mint marks, produced in West Point, Philadelphia, San Francisco and Denver mints, etc.

We have proof coin set buyers, local mint coin set buyers, and commemorative coin set buyers near where you live. We look forward to reviewing and appraising your coin collection once you get in touch with us.

      Q. I want to sell four coins? Can you arrange for an expert buyer to visit me?

      A. Four or five coins unless high value coins would be too small for a collection to warrant one of our numismatists to travel possibly several hundred miles to examine. In situations like these, it is best to use our insured mail in program. The program provides you with a free appraisal via pictures or list of your coins. You can do all of this from the comfort of your home. Once we receive the package, our buyer will carry out the final inspection. If you agree to sell, we will pay you immediately.

      Q. Can I get an appraisal over video chat?

      A. It is hard to examine a coin via video chat properly. Certain marks aren’t entirely visible and merit an in-person inspection. However, we can give you a rough estimate of what the coin(s) are worth if you send us high-resolution pictures or if coins are in NGC or PCGS holders.
