A previous note presented a few contemporary counterfeit shillings of Charles I. (Link). These either displayed the EBOR mint signature or showed a declaration type similar to the official Oxford Issues. Punch links suggested connections between the different types. Recently the British Museum has photographed and uploaded its Charles I counterfeit shillings. This note presents eight of the BM pieces and fits them into the previous scheme and also adds a counterfeit Tower issue shilling mm tun. Punch links now allow all of the counterfeits described in the two notes to be divided into two groups suggesting just one or two workshops produced them all.
