What classical numismatic group does

Classical Numismatic Group (CNG), legally Classical Numismatic Group, Inc., is a private numismatic auction house specializing in ancient and historical coins from Greek, Roman, Byzantine, Islamic, British, and world civilizations. The company operates from three offices — its headquarters in Lancaster, Pennsylvania (USA), and representative offices in London (UK) and The Hague (Netherlands) — and runs three complementary sales channels: live Feature Auctions with printed catalogs (current numbering in the 130s), timed Electronic Auctions conducted online (current numbering in the 600s), and The Coin Shop, a fixed-price e-commerce storefront of approximately 395 items across ancient and world categories. Underlying technology consists of an in-house bidding platform (auctions.cngcoins.com) extended to iOS and Android via Auction Mobility, plus an Issuu-hosted virtual catalog system for live auctions, with no disclosed AI/ML components.

CNG's business model is transaction-based. The company earns buyer premiums on successful bids in both auction formats, commissions/fees on consigned lots, and direct margin on fixed-price sales through The Coin Shop. Pricing is not publicly disclosed at the company level; individual lots carry presale estimates and starting bids. The go-to-market motion is event-driven, anchored on a regular cadence of scheduled auctions publicized through the company website, registered-bidder email notifications, and digital catalogs. CNG serves two principal customer segments on a horizontal basis: individual collectors and numismatists acquiring ancient coins for collections, and consignors (collectors and estates) seeking to monetize collections through auction. The platform supports global shipping and bidding, with no enterprise or institutional customer concentration disclosed.
