Incorrect. They are NOT both pieces of paper. The majority of the money supply isn't paper or any tangible object. 'Money Supply' is measured in varying ways, M0, M1 etc.,. and even the narrowest measure, M0, includes bankers deposits at the BoE. 'Money Supply' can include customers deposits at banks. A £1 note creates about £9 of 'money' because when it is paid into a bank the bank then lends some it to somebody else who gives to another person who pays it into their bank, which then lends it etc.,. The bank discount rate (known a Repo, Base or Minimum Lending Rate et.c, over the years) controls how many times the £1 can circulate.
