PETA

More recently, PETA ditched the two pennies and added a nickel.

A nickel?

“I’ve enclosed a nickel for you because I desperately need your attention and your help to waken the general public and public policy makers to a terrible tragedy,” the letter’s lead paragraph reads.

According to Anderson, the costs involved with purchasing and sticking two pennies to the top of the questionnaire, visible through the poly window, outweigh that of a nickel — surprisingly enough. But after nearly four years of using the nickel as an attention-getting device, and seven total years of employing coins altogether, PETA thinks it might finally have beaten its control.
