The Royal Numismatic Society is the UK's foremost society for numismatics – the study of coins, medals and related currency items.

Founded in 1836 as The Numismatic Society of London, today's Society is international in subject and membership. Its lectures and publications deal with Classical, Asian, Medieval and Modern coins, paper money, tokens and medals, and Fellows include scholars and enthusiasts from around the world.

Meetings are held on the third Tuesday of the month between October and June, usually at The Warburg Institute, 6pm to 7.30pm, and are open to all.
