The Royal Australian Mint as it appeared shortly after it was completed in 1965. It was commissioned to produce our "new" decimal currency...

"Mint your own $1 coin". Details of instructions at right.
Above is one of the Mint's more cunning ideas. You feed $2.50 into this machine, press the green button, and *thump*! ...out rolls a freshly-minted $1 coin. ...and the funny thing is, weird folks like me just keep feeding it $2.50 for a $1 return. Must have the bean-counters in paroxysms of glee.
