About Us

Since 1971 William M. Rosenblum has had a distinguished career in numismatics, specializing in all aspects of Israel, Palestine and Jewish numismatic material (ancient to modern), and ancient, medieval and modern coins, paper money, tokens and medals of the world. He has published over 250 auction catalogs and fixed price lists, is a member of numerous numismatic organizations, and has contributed to many numismatic publications. See some of William's career highlights below.

William is mostly retired now, but still has a substantial inventory of coins, banknotes, tokens, medals, and other numismatic items available. His son Brian and grandson Shimon, based in Lawrence, Kansas, have relaunched this website to make some of these materials available. You might think of us as Rosenblum & Son & Grandson Coins!

We pride ourselves in giving value for your dollar. 

We will periodically upload new inventory to this website, so please check back regularly, or subscribe to our mailing list to receive announcements about new listings.

Please reach out with any questions or let us know if you are looking for something in particular.

We look forward to hearing from you!
