when did australia stop using one cent coins
Australian one-cent coin The cent or penny, formally the one-cent coin, was the lowest-denomination coin of the Australian dollar, introduced on 14 February 1966 in the decimalisation of Australian currency until it was withdrawn from circulation in 1992 (along with the two-cent coin)[1][2]
Lincoln cent The Lincoln cent (or sometimes called Lincoln penny) is a one-cent coin that has been struck by the United States Mint since 1909. The obverse or heads side was designed by Victor David Brenner, as was the original reverse. The coin has seen several reverse, or tails, designs and now bears one by Lyndall Bass depicting a Union shield. All coins struck by the United States government with a value of 1/100 of a dollar are called cents because the United States has always minted coins using decimals. The penny nickname is a carryover from the coins struck in England, which went to decimals for coins in 1971.
