In 1940 Willocks McKenzie, a local lorry driver, found a small hoard of late Mediæval coins and rings beside the River Thame. The coins were ten groats and the rings were five ornate examples ranging from the 14th to the 16th centuries. The county Coroner declared them to be treasure trove and therefore Crown property. The Crown placed the hoard on permanent loan to the Ashmolean Museum. The most ornate ring was an ecclesiastical one incorporating a small reliquary. Its lid is decorated with a distinctive cross with two horizontal sections, similar to the Cross of Lorraine. Thame Town Council incorporated this cross into its town emblem.
