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 (The Big Bang Theory) In the original, unaired pilot of the series, the conception of the female lead was very different. She was called Katie, and was envisioned as "a street-hardened, tough-as-nails woman with a vulnerable interior". Sheldon and Leonard would "approach her with honesty, to draw the real, sensitive Katie out".[31] The role was played by Amanda Walsh.[48] However, the test audiences reacted to the character negatively, seeing her as too mean. Because of this, the character was changed, and the role was recast.[31]
