Adam Crum’s Finest Known

Finest Known, LLC was born out of the vision of Adam Crum, to provide the full range of coin services that today’s sophisticated customers increasingly demand. He sought out a major wholesaler that he has known as a friend and business associate for decades to form Finest Known, LLC. Combined, the new leadership team has over 150 years of experience in numismatics. This new partnership instantly strengthens the company’s infrastructure, provides access to a greater and more varied inventory than ever before, and dramatically expands the reach of the company’s network.

Monaco’s Evolution

After over 20 years as one of the country’s premier high-end retail coin companies, Monaco Rare Coins has become Finest Known. Adam Crum, the head of Monaco Rare Coins since its inception in 1998, has developed several strategic partnerships to access the largest array of modern, ancient, and rare coins the market has to offer to form Adam Crum’s Finest Known, a new direction and expansion into a full-service numismatic and precious metals coin company. We have expanded our rare coin inventory and strengthened our infrastructure to provide our customers with the finest service available.


Exquisite, Historic Rarities

Finest Known specializes in rare coins, ancient coinage, shipwreck treasure, currency, documents, art and artifacts of historical significance. Customers have telephone access to our experienced team of Numismatic Advisors for one-one sales consultations, or can shop online inventory on our secure e-commerce website. Coming soon is Finest Known Auctions, a 24/7 online auction platform for coins consigned by collectors, investors, and dealers, with future live auctions featured several times a year. Later this year, Finest Known will launch Numismatic University, an online educational platform to educate and inform, available 24/7/365, any time on any device.
