The Peterborough Numismatic Association, which is now known as the Peterborough Numismatic Society, was formed in Peterborough, Ont. in 1951.
The society has been active in the communities in and around Peterborough. It has issued two medals, one featuring the world’s largest lift lock located in Peterborough. The lock was built to overcome a 65-foot difference in water levels on the Trent Canal which connects Lake Ontario to Georgian Bay and Lake Superiour.
The other medal issued was in 1983 when they hosted the annual Ontario Numismatic Association convention at the (torn down) Rockhaven Motel. The medal was struck in both bronze and silver (Bronze : 62, Silver : 30)
