About Us

We are a error coin business specializing primarily in major mint errors. We buy and sell mint errors of all values, whether the error coin is worth a few dollars or is worth tens of thousands of dollars--we buy and sell it all. Knowledge, honesty, and great service are how we seek to serve our customers. We want to treat you the same way we would want to be treated, and it is on this core value that our company is built.


About Jon Sullivan


The company is owned by Jon P. Sullivan, who has been a coin collector since age 9, and a part time error coin dealer since 2003, and full time as a dealer exclusively in major mint errors and related items since 2014. 

He is a member of ANA, CONECA, FUN, and has actively participated in many other club events and numismatic functions. We are both NGC and PCGS authorized dealers. 

Jon also has written numerous articles for publications such as CONECA’s Errorscope, including articles on mint errors, the minting process, varieties, as well as U.S. coins, and is both a coin collector as well as a dealer. His interest goes well beyond just error coins and variety coins, as all areas of numismatics are connected and fascinating to study, and coins are one of the few pieces of history you can hold in the palm of your hand.
