Celtic Copper Alloy Coin Minting Technology: Experiential Approaches

Lawrence Herzman and
Monika Townsend (US)
In this paper, details are presented for three technical approaches that can be employed in the reproduction of Celtic coins from Britain: 1) the use of pellet trays to produce coin blanks of standardised weight; 2) the use of successive iterations of clay moulds to shrink coin design images while retaining clarity; and 3) the use of a low-carbon steel die that was heated to a plastic state and struck with a cast bronze slug to...
