who came up with the design idea for the penny
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.
Penny (Canadian coin) Production of the penny ceased in May 2012,[1] and the Royal Canadian Mint ceased the distribution of them as of February 4, 2013.[2] However, like all discontinued currency in the Canadian monetary system, the coin remains legal tender. Once distribution of the coin ceased, though, vendors were no longer expected to return pennies as change for cash purchases, and were encouraged to round purchases to the nearest five cents.[3] Non-cash transactions are still denominated to the cent.
