We have been very busy adding inventory to this website, and have finally got all our inventory up for sale so that there are now well over 750 error coins on the site! It has taken quite a long time to get everything organized, photographed, priced and list on the site, and we are very pleased with the results. The coins are organized by date and denomination. Click on any error category and you will see that there are a number of ways to view the coins, whether by year, price, alphabetically, or newest listing.
We are always getting fresh inventory in. Sometimes it's a collection, sometimes fresh coins from a coin show, or sometimes from other sources, but we will keep you alerted if you sign up to the "News" newsletter. We will alert you when we've added a large group of coins to the site, eBay, or have other important news to share. You can unsubscribe at any time using the link at the bottom of the newsletter (and we of course will never share your email with anyone.)

We have added an interesting youtube video to the site which is well worth your time to watch. The film is a circa-1920 silent video showing the minting process at one of the U.S. Mints. This is a very interesting video because it shows a number of minting processes and procedures which were in place at that time, as well as the conditions that the employees worked under, the equipment they were using, and also how much "hands on" work was done. Machines were not used nearly as much as they are today, although there was obviously a great deal of machinery in use.
A few notes about the film:
1.Mute it--the background sound is obnoxious.
2.Note the used of scales to weight EVERY planchet. This would explain why clips are extremely rare on early 20th century coins.
3.The planchets being "ring tested" by hand. Until I saw this film, I never knew that was done. Very interesting, and it also would explain why defective planchet coins, off-metals, etc, are nearly unknown on early 20th century coins.
4.The use of the massive screw press for hubbing the dies.
Here is a link to the video (I recommend you mute the sound--the film has some obnoxious background music.) https://sullivannumismatics.com/information/videos/circa-1920-minting-process-us-mint
