Scotland and England had the same coinage with the same denominations, except if you cashed a Scottish one pound note in England, they deducted sixpence in change. This was in the 50’s, Don’t know if they still do...but used to rile folks in my day. The old money started with a farthing, then a half-penny (pronounced hape-nay), a penny, tuppence was two single pennies, then a threepenny piece(pronounced thrup-nay), fourpence was 4 pennies, likewise fivepence was 5, then a sixpence piece, then a shilling piece(12 pennies), then a 2 shilling piece called a sovereign, then a half crown, which was two shillings and sixpense. Now its all metric.
Hmmm ... IIRC (It has been 10 years) now the coins are a penny, a tuppence, a five-pence, an 10 pence, a 20 pence, a 50 pence, a pound, a two-pound, and then there’s paper ...
IIRC, the common paper was 5,10 and 20 pound notes.
