About Us

A New Name, Built on Old Roots

Rumnicoin was founded in 2024, but our legacy in world numismatics spans over six decades. As a family-run business, we bring a combined 100+ years of expertise to collectors, investors, and numismatic enthusiasts around the globe.

Our founder, Chris Rumney, established himself as a trusted figure in the trade, managing auctions and supplying rare coins to prestigious auction houses and collectors across Switzerland, the UK, and beyond. Since 2019, we have curated and brought to market over £10 million in realised hammer values, handling some of the world’s most significant collections with discretion and expertise.

Our Expertise

Rumnicoin specialises exclusively in all areas of numismatics, combining deep market knowledge with an efficient, client-focused approach. Unlike larger, London-based houses, we offer:

  • Competitive buyer’s premiums of 15%
  • No seller fees (in most cases) for clients looking to bring their collections to auction
  • Seller commissions offered for standout material
  • Personal service backed by decades of trust and reliability

With us, you keep more of your money and whilst maximising the potential of your valuables.

A Proven Track Record

Our founder previously managed a prominent auction house in Switzerland for seven years, establishing relationships with Swiss institutions, banks, and global clients. As a major supplier of world coins to renowned auction houses like DNW, Roma Numismatics Ltd, Baldwin’s, and The Coin Cabinet, we are proud to have played a key role in shaping the global numismatic market.
