I think if £4 is being paid for a cornet, a £1 for the flake is neither here nor there. £4 may be justifiable for the highest quality, organic ice-cream made with the freshest natural ingredients. From the average ice-cream van, no. I'd have told mine to be patient and we'd stop at a shop.
20 shillings to a pound.
12 pence to a shilling
I recall ha'pennies pennies, threepence, sixpence, shillings, two Bob bits (two shillings), half crowns (2 shillings and sixpence), ten shillings notes (ten bob), pound notes and a denomination called a guinea which was equivalent to one pound and one shilling.
I recall all that because upthread somebody referred to 1s6d (one shilling and sixpence) in new money that was 7.5p. A great uncle used to give me a half crown after church on Sundays when I was about 4. It was very, very generous and special to have such a big, heavy, silver coin. Equivalent to 12.5 new pence!
We spent hours rubbing pennies as children due to the different Kings and Queens. Queen Victoria (occasionally), Edward VIi (occasionally), George V, George VI and E II. Our children never had that little insight into history seeing only E II on coins.
Irrelevant I know but the references to old and new money made me think of it.
