UK portal the-saleroom.com (owned and operated by ATG Media), and the US cooperative Bidsquare are now inviting auctioneers to list on each other's platforms in the hope of reaching new customers in both markets.
From October 1, UK auctioneers listing their content on the-saleroom.com can pay £250 per catalogue to have their content mirrored on Bidsquare.
Potential buyers who find items on the US site will be directed through to the-saleroom.com should they wish to bid - and visa versa.
Bidsquare was launched in September 2014 by a cooperative of auctioneers hoping to control the fees, the content and the vetting of buyers when selling to an online audience.
The six founding members of the 'curated' site - Leslie Hindman (Chicago), Rago ( New Jersey), Brunk (North Carolina), Cowan's (Ohio), Pook & Pook (Pennsylvania) and Skinner (Massachusetts) - have since been joined by a network of more than 80 north American auctioneers.
Bidsquare CEO Allis Ghim said: "There is great synergy between the North American and UK art and antiques markets. Bidsquare and the-saleroom.com are playing an important role in providing buyers access to the most credible sellers of antiques, fine art and collectables."
Last year sales totalling $140m were transacted via the-saleroom.com.
CEO Anne Somers said: "Our position as a leading auctions marketplace in the UK means we will be able to offer Bidsquare buyers and collectors access to a huge range of European art and antiques on one easy-to-use portal.
"At the same time, we are thrilled to be providing additional exposure to an international audience to the auctioneers who work with us."
