Four Iron Age coins were discovered by metal detectorists near Monkton in the 1980's. Three of the coins were made of cast bronze and dated to c.100-90 BC. They were of Trinovantian type and one was in a poor condition, showing evidence of corrosion. A fourth coin dated to c.23-17 BC and was of Cantian type. This coin is thought to have been made of silver. It is uncertain where these finds are now located
