Introduction to Coins

Hammered and Milled

Old coins are classified as 'hammered' or 'milled'. Hammered coins were made by hand striking a die with a hammer. Milled coins were made by machine. The first type of coin machine was the 'mill and screw press', and the term 'milled' has stuck for all machine made coins.

Celtic Coins

Celtic coins are very rare and their denominations are not known. They were only produced in the hundred years before the Roman invasion. The Taynton area belonged to the Dobunni tribe and the club has found several of their coins.

Saxon Coins

Saxon Coins are very rare. The first native Saxon coin was gold and called a Thrymsa. Thrymsas were minted from about 630 to 675, when they were replaced by a silver penny, known today as a Sceatta.

Medieval Coins

At the start of the medieval period the Normans adopted the existing Saxon mints with the penny remaining the only coin. The penny was made with a cross on its back to facilitate the coin being cut into halves or quarters to make half-pennies and farthings. Farthing means 'a fourth part' in old English.

Later in the period higher denomination coins arrived, including the groat and the noble.
