Should The US Produce $1 & $2 Coins Or Currency?

$2 bills have the fewest produced annually. In both 2014 and 2014, just 32,000,000 were produced each year, with 179,200,000 in 2016 and none in 2017. In 2018 just 51,200,000 were made. This is a fraction of the quantity of the more commonly-found notes, making them an interesting keepsake for youngsters.
