What NUMISMATICA GENEVENSIS does

Numismatica Genevensis SA (NGSA) is a Geneva-based auction house and numismatic dealer founded in 1988, specializing in prestigious collector coins and medals spanning Greek, Roman, Celtic, Islamic, Medieval, and Modern periods. The firm operates a saleroom-style auction business with 23+ completed auctions, a live bidding platform (ngsa.ch/live-bidding) integrated with third-party auction partners biddr and Six Bid, and an E-Shop (shop.ngsa.ch) launched in October 2024. NGSA generates revenue primarily through auction commissions on the sale of coins and medals, complemented by direct sales via the E-Shop and professional appraisal/expertise services for collectors and institutions.

The company serves four core customer segments: private collectors (the primary segment), museums and institutions, banking and financial institutions in Switzerland and abroad, and high-net-worth collectors in the Middle East served through the Dubai-based NGSA DMCC subsidiary. Its go-to-market is sales-led and relationship-driven, supported by membership in 9 professional numismatic societies (ANS, IAPN, SENA, SGN, SSN, ANPS, FFA, FDA, NVZ) and curated exhibitions such as Coins of Islam (Abu Dhabi, 2020) and Minted Narratives (Saudi Arabia, 2025). The team of 7 includes expert numismatists who advise on buying, selling, and authentication, anchored from Geneva headquarters (Rue François-Bellot 4) and the Dubai regional office (Almas Tower, JLT).

NGSA has set multiple world records for individual coin sales, including the Hadrian aureus (over 2M CHF in 2008), the Brutus aureus (approximately 2M EUR in 2024), and the Centén Segoviano 1609 (approximately 3M EUR in November 2025), reinforcing its positioning in the upper tier of the numismatic auction market. The business is privately held by founders/management, operates as a Swiss Société Anonyme, and has no external funding or parent company per the available data.
