Metal detectorists unearthed a hoard of ancient treasures, including a medieval coin, during searches in Evenwood. Mr Richardson said the silver pennies, often called long cross pennies, are common medieval coins typically about 18-19mm in diameter. ADVERTISEMENTHe added: “The obverse usually features a stylized portrait of the King, while the reverse features a long cross with three pellets in each corner. “They were produced with a long cross extending to the edge of the coin on the reverse to prevent clipping. This translates as ‘Truth, the daughter of Time’ and is only found on the coins of Mary Tudor.
