Usage notes
- The use of bob for shilling is dated slang in the UK and Australia, since decimalisation. In East African countries where the currency is the shilling, it is current usage, and not considered slang. OED gives first usage as 1789.
- The use of bob to describe a 10-cent coin is derived from the fact that it was of equal worth to a shilling during decimalisation, however since then, the term has slowly dropped out of usage and is seldom used today.
