A pair of the rare and popular 1943 copper cents were recently discovered, and certified by NGC. The coins are worth many hundreds of thousands of dollars each, and are a remarkable discovery! 1943 copper cents are the most valuable mint error for U.S. coins, with the 1943-D being the most valuable of them all. These are not worth as much as the 1943-D, but are still likely to bring well over $250 …

The year is off to a good start in our opinion, with our sales being brisk, major auction results looking relatively strong, and overall good activity in the market. We have been through a number of major coin shows, auctions, and have been able to get a feel for how the error coin market is doing.  There are strong areas and weak areas, with some of the more common (even if expens …

Above: The Baltimore coin show bourse floor. We’re finally catching up after a busy Baltimore coin show last week. The show, located in Baltimore, Maryland, and held 3 times a year, is one of our favorite shows of the years, due to its excellent location, which brings in lots of both customers and dealers from all over. This year we were wondering how good the show would be, since the coin market …

This very short article on coin grading and honesty among coin dealers and collectors. Two of the biggest problems in the coin market, as laid out by Q. David Bowers, are current grading standards and honesty in the hobby. Here is a link to the article: http://www.coinworld.com/news/us-coins/2017/02/be-honest-when-making-sales-pitches-to-customers.htmlAlthough coin grading does not effect the erro …

Error coin collecting and the error coin market have always had their ups and downs, with both the popularity and prices of errors going up and down. It’s a “seesaw” effect, which is seen in all collectibles and areas of investment just as it is in the error coin market. However, even knowing this, it can be disconcerting to see a coin that was selling for $1,000 drop in price to $700, especially …

Now that the summer is over, vacations are done, and we are getting well into the fall season, coins are back in the minds of collectors. This is true for the numismatic hobby at large, as well as for error coin collectors.  Coin collecting always picks up appreciably beginning in the fall and going on through winter and into spring. We’ve noticed the change here at Sullivan Numism …

The ANA World’s Fair of Money is right around the corner, and we will be attending!

(Image Courtesy of Coin World.)Another $1.25 Mule has come onto the market! This is one of the best known and most popular mint errors, with examples typically selling for $75,000 to $150,000. Simply defined, a mule is a coin which was struck with the dies of two different coin denominations.Such a coin has one denomination on one side and another denomination on the other. This has only occurred …

The Baltimore whitman coin show was a decent show this July, although as with all summer shows they aren't nearly as active as shows held at other times of the year. It was "as expected", with moderate buying and moderate selling, but overall satisfactory with enough of both activities to make the show well worth attending. Some of our regular customer were there, although a good number were …

We will be set-up at the Baltimore Whitman coin show this weekend in Baltimore, Maryland. Our table is "Sullivan Numismatics" #340, and we will have hundreds of rare mint errors with us for sale. This is slightly smaller than the winter or fall Baltimore shows, but is still worth attending as there will be hundreds of dealers in attendance. http://expo.whitman.com/baltimore-summer-expo/ If yo …
