International Auction Galleries has been a leading Australian Auction House for 39 years, and the first Numismatic Auction house in Queensland. Established in 1985, IAG has a proven track record with industry leading clearance rates and a reputation for honesty, integrity and service, treating each consignment with the upmost care and privacy.

IAG’s commission rates are the most competitive in Australia, with NO SELLERS COMMISSIONS OR FEES (0% Commission), and NO other compulsory charges! With others charging up to 40% in total commissions, fees and charges, you will SAVE by selling with IAG. Lower fees means both Buyers and Sellers are the big winners in our auctions!

We specialise in high quality "boutique" style live and online Coin and Banknote Auctions with a focus on selling the rarest and the highest quality Coins and Banknotes, as well as unreserved lots from $1 and everything in between! Our two Signature Live Online auctions are a yearly numismatic highlight, attended by many of the biggest dealers and collectors in Australia. As of 2024, IAG has held more than 280 Live, Online and Postal Sales over 39 years and achieved well in excess of $175 Million in sales.

We hold at least four major Auctions a year, which means you have more options when it comes to selling, and have a shorter wait time for payment. Our auctions continue to set record prices, and we currently hold several pricing "World Records", including the highest price ever realised for any Australian Numismatic Item at $1,909,000 (this is also the highest price achieved for any item at any Numismatic Auction in Australia). In 2008 IAG sold 2 single items in consecutive sales for over $1,000,000 each. Our last 25 signature live auctions have broken countless world records, and we have sold in excess of $50,000,000 in these auctions alone!! (See the Download section for our current or previous Catalogues and Prices Realised as well as past Auction results and highlights).

IAG is the number one Australian Numismatic Online Auction house. With regular Live Online auctions in 2012, IAG was the first Auction House to run completely live Online auctions, with a strong Online auction presence dating back to 2004 and having offered hundreds of thousands of lots to tens of thousands of clients from right across the world. IAG’s proprietary in-house developed Live Online Internet Auction program is not only market leading and is FREE to use and bid with! As IAG has developed and run their own system independently, they are able to expand and evolve it in all aspects of Numismatics whilst continuing to provide innovative and better ways to buy and sell as the market changes, whilst ensuring that your data is private and not shared anywhere or with anyone.

IAG's Numismatic Specialist, CEO and Managing Director Paul Hannaford has been a Professional Numismatic Dealer for 39 years, and has brought IAG to a prominent position as one of the leading Auction House in Australia. He is considered a numismatic expert on Australian Pre Decimal Coin and Banknotes, and has been involved in providing information for numerous Numismatic price guides. Paul is a past National President of A.N.D.A. (The Australasian Numismatic Dealers Association), having held that position for a record 6 years, and is the longest ever ANDA Committee member having served for the last 26 years and counting. In addition to being National President, he has also held the position of Vice President for a number of years, as well as chairing other specialised numismatic related ANDA committees including the Ethics and Good Conduct Committee (E&GCC).
