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 …

With the stock market bumping up and down at all-time highs, gold and silver staying relatively steady, and overall the economy somewhat “mixed”, where is the error coin market right now? At this point in time, it is generally good for most error coins. Some error coins aren’t selling well, while others we have trouble stocking due to none being for sale on the market, or simply prices movin …

Here is a interesting article on the 1943 steel cent strip, written by David Lange of NGC. The article gives some of the background of the 1943 steel cents, and then talks about how the pieces of steel cent strip came onto the coin market. We have handled many pieces over time, and all of it was rusty to some extent--this article will explain to you why that is. http://www.coinweek.com/deale …

There have been a lot of Chinese counterfeits coming into the coin market over the last 5-10 years, and occasionally error coins have been the target. Recently, we came across this lot of double-struck Morgan dollars on eBay, with a "Buy It Now" price of $135. They were being sold as "copies" and not as genuine, but the problem comes from them not being marked in a permanent way as being cop …

If you have never attended the ANA Summer Seminars, we highly recommend you do so! It is a must attend event for any serious numismatist, with classes on numerous subjects, and an excellent class on mint errors and varieties, which is being taught by well known die variety researcher and expert James Wiles. Below is a link to more information about the Seminars, and how to register. This is a re …

It is surprisingly how many people still use vinyl 2X2 coin flips to store their coins. Dealers and collectors alike are guilty of this, and the result are coins with a light hazy film of green PVC residue across the coin's surfaces, and sometimes even permanent damage to the coin. These PVC-coated coins have to be conserved in order to remove the damaging film of green. If you have any coins in s …

Beware of the many fake coins struck on nails on eBay. They came out after a dime on a nail recently sold for over $40,000 at auction, and these counterfeiters are trying to rip off collectors with these fakes. Genuine examples will always be certified by PCGS or NGC--none of the counterfeits will be. The coins are coming out of Asia, and are found on many different denominations of U.S …

Baltimore Coin Show Report for Mint Errors: March 30th-April 2nd by Jon P. Sullivan This coin show held every Spring, is one of our regular shows which we attend every year. It is typically one of the very best coin shows of the year for both buying and selling, and we look forward to it to do business, see customers, and also to take the “pulse” of the market. This year we saw a few thi …
