about sullivan numismatics, inc
We deal in mint error coins, with 20 years experience as specialists in mint error coins under the company name Sullivan Numismatics. We buy and sell mint error coins of all values, and specialize in primarily United States mint errors made from 1836-present, and valued from $25 to $50,000 in value—but we also handle some world and early U.S. errors as well.
Our sales venues include a handful of major coin shows (see our “Show Schedule” for show set up locations), as well as through the website www.sullivannumismatics.com. We also offer coins on eBay, and fill customer want lists.
