About Us The British Numismatic Association represents the interests of more than eighty firms located throughout the British Isles.
The Coin trade in Britain has come a long way since the British Numismatic Trade Association (BNTA) was founded 35 years ago, indeed this is true of numismatics worldwide, but the UK has certainly not lagged behind.
About BNTA
The Field
The whole field with which BNTA concerns itself has expanded marvellously. Thirty-five years ago there were three main areas – coins, commemorative medals and ODM (orders, decorations and medals), Now banknotes, share certificates and the like have added to the wealth of collecting interest, and it is increasingly common to find small antiquities, ancient cameos and gems (glyptics) being offered at coin fairs.
