Charles Hanson, founder of Hansons, has hired specialists Adam Staples and Lisa Grace as consultants and will hold three auctions a year under the new Historica banner.
The first auction will be held on November 29 with 600 lots including three rare coins that have links to the Midlands.
The bolt-on department will focus on UK antiquities from the iron age to the 17th century.
Hanson said: “I have been looking at this area for some time but it has taken me two years to find the right people.”
Staples and Grace have worked in the field of antiquities and coins for almost 36 years between them with experience of working with museums and the UK Detector Finds Database.
Hanson said he respected London based TimeLine Auctions who have been “leading the way” in antiquities and said there was room for a provincial auctioneer in the market.
He acknowledged the potential legal issues in the area of antiquities and said: “We need to be as sharp as we can on legislation. It is about understanding and respecting heritage.”
Staples added: “We are fully aware of all the treasure laws. We will not be involved in anything illicit or anything that tarnishes our reputation.”
Hanson, 38, set up his business 10 years ago and employs 22 full time staff and a group of expert consultants.
