Please stop printing paper dollar bills, and instead bring out 1 and possibly even 2 dollar coins to replace them. As the GAO as stated many times throughout the years, it is more affordable to do, and the coins last much longer than the paper bills.
The $1 coin is durable and environmentally-friendly. Most dollar bills currently in circulation were made within the last three years. Dollar coins officially last 30 years. To put it another way, a single dollar coin can do the job of at least 17 dollar bills over the course of its lifetime. When the coin, which is made almost exclusively from existing scrap metal gets pulled from circulation, it is 100 percent recyclable. In contrast, the government disposes of 7,600 tons – that’s 15.2 million pounds – of currency paper each year.
