But sales tax is different in all states. Each store would have to sit down and calculate the prices out perfectly so that when the sales tax was added, it would come out perfect. Sounds unfeasable to me. In 2004, there were 6,836,000,000 pennies minted. Thats more than all the nickels, dimes, quarters, and dollar coins combined minted in 2004. So it doesn't seem like the penny will stop being minted for a long time
