Coin & numismatic auction software for serious collections.
Sell coins, bullion, and currency on a platform that understands grades, certification, and spot price. Unovance Global gives you grade-aware cataloging, high-value bidder vetting, and a branded marketplace you own outright.
Numismatic selling lives and dies on trust and detail. A buyer spending five figures on a key-date coin wants the cert number, the grade, the slab photo, and the population data in front of them before they commit. Unovance builds that detail into every lot record, so PCGS and NGC certification, mint marks, and series information sit right where bidders expect them.
The catalog runs from raw bulk lots to trophy rarities and bullion, and each tier can carry its own bidding rules. Vet bidders on premium gold and rare type coins, open mid-grade sessions to a wider audience, and let invoicing account for bullion content, buyer's premium, and insured shipping without manual reconciliation.
Most importantly, the collectors you earn stay yours. Instead of feeding a third-party marketplace and renting its audience, you build a repeat numismatic community on a platform that carries your name, your terms, and your data.
Built for the realities of selling coins and currency.
Grade-aware cataloging
Capture PCGS and NGC certification numbers, grade, mint mark, year, and population data per lot, with cert-image galleries so bidders evaluate the slab before they bid.
Vetting for high-value lots
Require deposits, identity verification, or pre-approval on premium gold, rare type coins, and bullion lots so only qualified bidders compete on the pieces that matter most.
Formats that fit numismatics
Run timed online sessions for bulk and mid-grade material, live webcast events for trophy coins, and sealed-bid or extended-bidding rounds for marquee single-owner collections.
Settlements that respect spot
Configurable buyer’s premiums, bullion-aware invoicing, insured-shipping workflows, and consignor settlements that reconcile cleanly against hammer and reserve.
Frequently asked questions
Can the platform store grading and certification details?+
Yes. Each lot record holds the grader (PCGS, NGC, ANACS, and others), the certification number, assigned grade, mint mark, and series details. You can attach slab images and link to population reports so bidders verify authenticity directly inside the listing.
How do you protect high-value gold and rare coin lots?+
You control bidder access. Require registration deposits, identity verification, or manual approval before bidders can place bids on premium lots, and apply different vetting rules to bullion, key dates, and trophy coins within the same sale.
Which auction formats work best for coins and currency?+
Timed online auctions clear volume and mid-grade material efficiently, live webcast sessions drive competition on trophy pieces, and sealed-bid or extended-bidding formats suit single-owner collections. All of these run from one branded platform and one bidder base.
Do we own our bidder list and collector relationships?+
Yes — that is the core of the Unovance model. Your bidder data, buyer relationships, and brand stay yours. You build a repeat collector community on a platform you own instead of renting an audience from a marketplace.
