This manual cash register, ancestor of today’s computerised tills, can be dated accurately to the 1960s, before Britain changed to decimal currency in 1971. Although it has keys designated for pennies and halfpennies, it lacks the farthing or quarter of a penny, which was abolished in 1961. The precursor of decimal currency was the ‘pounds, shillings and pence’ system (LSD), with the shillings and pence represented by ‘s’ and ‘d’ respectively. One pound consisted of 20 shillings, and each shilling of 12 pence. The keys on this cash register range from a halfpenny to 11 pence, and then from 1 to 10 shillings (50 pence in today’s money). There is no £ key, indicating the high value of the pound at the time. Then as now, prices were often just short of a whole number, requiring the till to be opened to provide change. This announced a sale by ringing the bell at the side of the machine, and thus discouraged pilfering.
