International Auction Galleries - Queensland’s first and foremost numismatic auction house - was established in 1985 to fill the void of a smaller, high end ‘boutique style’ auction house. Our auction sales; of which we do two major Signature Live and two Live Online auctions a year, are always seen as yearly numismatic highlights. As of 2025, IAG has held more than 285 Live, Online and Postal Sales, and now in their 40th year of operation, have achieved worldwide renown with record breaking auctions totalling over $185 Million in sales. IAG has a proven track record and widely respected reputation for honesty, integrity and service, treating each consignment and each customer with the upmost care and privacy.

Our Coin and Banknote Auctions continue to be one of the market leaders in rare and high end numismatic collectables with our auctions always breaking new records. We hold several pricing World Records, including the Highest Price ever realised for any Australian numismatic item at $1,909,000 (also the highest price achieved for any item at any numismatic auction in Australia). In 2008 IAG sold two single items in consecutive sales for over $1,000,000 each. Our last 20 Signature live auctions have broken countless records, and we have sold in excess of $40,000,000 in these sales alone!

With industry leading clearance rates, the fastest and most secure guaranteed 30 day vendor payments (with all funds held in our Trust Account) along with our friendly and efficient customer service and ZERO sellers commission rates for all vendors shows why IAG is Australia’s number one numismatic auction house!
