I had a chat with the guy on the press, I asked about the set up, dies and pressure used, his reply was that it was a press used for general coinage relocated specifically for the visits, only one set of dies had been made, the striking pressure was reduced down from that normally used to prolong the life of the die and thought they would strike around 100k in total.
Has anyone else been on the Tour, are there any other designs of £1 coin or other denominations that have been struck by Visitors there
