Numerous ancient Roman coin molds were found in Castleford, West Yorkshire, England (see map below). It is unclear whether these molds were used to create illegal forgeries or, less likely, authorized emergency replicas. These sanctioned replicas could be used to pay troops on the Empire’s outer reaches and would be later replaced once the authentic currency arrived. (The video below describes ancient molds.) https://www.dailymail.co.uk/news/ar...s-committed-crime-punishable-crucifixion.html
Very interesting, however it would have been more educational if they actually showed photos of the molds and discussed their findings.
Many of these Roman molds are now on display in Castleford https://www.bbc.com/news/articles/ce8yer43562o
