In the United States we have struck coins for foreign countries since 1876. Since then, the United state has struck well over 100 years of coins for foreign nations, and in the process has minted a lot of U.S. coins overstruck on other country's coins. Some are struck on just the planchet, while others are struck on a already struck coin (creating a double-denomination.) All of these are generally scarce, and there aren't any that are "common." Double-denomination coins are always scarcer as a rule than coins which are simply struck on the wrong planchet. 

The error occurs when a planchet or already struck foreign coin accidentally is struck with another nation's coinage dies. The result is a coin struck on another nation's coin planchet or a coin struck on a struck foreign coin (a double-denomination.) Some examples of these can be seen in the links below. 

While this error type has occurred in the United States, it also has occurred for other nations as well, who also strike coins for nations other than their own. A good example of this is the British Royal Mint, which is the largest producer of coinage in the World. They strike numerous coins for other countries, and as a result, they make off-metals and double-denominations on other nation's coins. Here is a link to some information about the coin's they produce for foreign countries.

So, anytime you are trying to attribute an off-metal or double-denomination which does not match up with a coin from it's nation's coinage, do some research and you may find it is in fact struck on another nation's coin or coin planchet. 

Here are some examples of U.S. coins struck on other nation's coins or planchets.

There are numerous other examples, including U.S. coins struck on foreign gold, silver, nickel or other metals, as well as numerous examples of both off-metals and already struck foreign coins. Some collectors collect these by finding a favorite country or continent and collecting U.S. coins struck on foreign coins from those countries or continents, while others will simply try to get "one of each" of every known basic type (U.S. cent on philippine 10c; U.S. cent on Argentina 10c, etc.) 

Coins struck on other foreign coin planchets and struck coins provide and endless array of interesting and varying Mint mistakes, which leaves the opportunity to find or discover something new (such as a new U.S. on foreign) as a possibility.

The ANA World's Fair of Money held August 16-20, 2022, in Rosemont, IL, was a resounding success both for us and for other coin dealers at the show! Sales were high, with collectors buying, and dealers having strong wholesale activity. Some dealers reported some of their strongest sales ever, and we had one of if not our best Chicago show ever (for sales.) The coin market is strong, and activity is healthy both on the retail and wholesale levels. Mint errors were for sale at the show, but generally were difficult to purchase as prices were often higher than we could pay. We will pay strong prices for any mint errors, but if a coin is "overpriced" in our opinion, we aren't going to buy it because we wont be able to offer it to our customers at a good value. 


We saw many mint errors at the show, although only purchased a relatively small number. Buying was somewhat tough. We did pick up some great coins though, and they will be showing up on our website in the coming days, and months. If you are not subscribed to our email alert, we recommend it, since subscribers get an email when we offer the fresh mint errors on our website, and coins often sell quickly when we list them.

There were a lot of customers with questions about their coins--is it authentic? What kind of mint error do I have? Is this 1943 copper cent real? Those are some of the many questions we answer at shows, which is part of the work of a coin dealer. There have been a plethora of (probably Chinese) counterfeit 1943 copper cents on the market of late, which although they are easy for a well informed collector to determine that they are fake, unfortunately many beginners are taken in by them. When in doubt, it's best to buy a coin certified by a major 3rd party grading service, or at least as an expert on the coin in question. 

It was great to see so many collectors at the show as well. There were a number of young collectors, and we also have started noticing more and more young coin dealers over the last few years--this is a good sign for the hobby, and hopefully this trend continues. Additionally, mint error coin club CONECA had a table at the show--if you are not a member of CONECA, you can join on their website, which we recommend.

The show was held at the Donald E. Stephens Convention Center in Rosemont, IL

FUN July Coin Show 2022

The Summer slowdown which often occurs in July really never hit us—we’ve been buying and selling a lot this month. This is largely because collectors are still actively building their error coin collections, but also because we have had a lot more mint errors to offer of late. During 2020 and 2021, most coin dealer’s inventories quickly became rather small. Shutdowns related to the Covid pandemic, such as no coin shows, dealer’s with coin shops seeing fewer coins walk in, and just less activity amongst people putting coins up for sale led us and other dealer’s to have greatly reduced inventory sizes.

 

Having fewer coins to offer customers will inevitably lead to fewer sales, but this has changed this year, and we now have the largest inventory (and it’s quickly growing) that we’ve had since early 2020, which is good news for us and good news for our customers. We have many major errors, as well as a quickly growing stock of less expensive errors. The coin market has largely returned to a normal, healthy level of both buying and selling.

 

We were set up at the FUN coin show in Orlando, Florida this month, and it was an excellent show, with a good amount of buying and selling. We sold more than we expected to in fact. Other dealers at the show dealing in “non error” coins largely reported having good to very good (and no, that’s not a comparison to the grading scale) shows.

 

Our next show will be the ANA World’s Fair of Money, which is being held the middle of August in Rosemont (Chicago), Illinois. It’s one of the largest coin shows of the year, and promises to be a great show once again. If you are there, look up our table “Sullivan Numismatics”, table #1529.

 

If you’ve not seen our articles, we now publish occasionally write articles on mint error coins for PCGS’s “Rare Coin Market Report” or for PCGS’s website. They can be viewed at: https://www.pcgs.com/news/search

2022 Central States and the Error Coin Market Sullivan Numismatics

A few weeks ago the Central States coin show was held in Schaumburg, IL. It was the first time the show had been held since the 2019 show was held, due to the events over the last few years. It was great to be back at the show, and especially since it was so well attended both with dealers and collectors. Admittedly, it has historically been a slower show for mint errors (although a great show for dealers in U.S. coins generally.) However, this year we had possibly the best Central States show we’ve ever had, with a decent amount of both buying and selling.

 

Attending shows in different parts of the United States brings a somewhat different group of dealers and collectors. Many dealers travel to all the major shows regardless of the location, but there are always some dealers who never make it to shows other than relatively local ones. Such is the case with Central States, and it was nice to see some of our local customers as well as dealers we do not see as often at other shows. Traveling to shows across the U.S. allows us a more broad opportunity to acquire mint errors, as well as to sell to customers, and so we try to attend shows from the West Coast to the East Coast. 

 

Recent major auctions have been overall quite strong. Prices for lower value pieces (under $500) has moderated somewhat (they were to the moon high prices over the last year or two) and are now much more in line with what historical pricing has been. Middle priced items in the $500-$5000 range are generally strong, with only certain error types or series not participating in the strong price trend. Scarce off-metals and the like have been going for solid prices most of the time. High end coins, in the $5,000+ category are also strong. Some of the prices we’ve seen of late have been moon money, while others are just selling for “full price.”

 

Overall, the market is strong for most mint errors, and although there are certain errors or types which are selling at more traditional, lower prices, probably 70% of coins are selling for strong prices in our opinion.

 

We do our best to keep prices at fair, moderate retail levels, and generally “ignore” prices that are aberrations from the average price trend for a particular error type of category. We price based upon a number of factors including:

1.Historical value

2.Auction prices realized

3.The cost to buy coins from any of our many sources

4.The particular coin’s attributes are all taken into consideration—is it the finest known, unique, or otherwise special—or on the flip side is it none of those things and might even have a problem or two, and so deserve a lower price than one would typically expect.

 

Accurate and fair pricing is something we continually strive for, and our goal is to always give our customers a good value. 

 

Our next coin show will be the Baltimore this June. If you are planning to attend the show, we looking forward to seeing you there! In the meantime, keep an eye out for new items being listed on our website over the coming weeks, and also if you have not yet signed up for our email list for mint errors, consider signing up so that you will get an email when we list fresh coins.
