In Australia we got rid of the one and two cent coins 30 years ago because the buying power of the ten cent piece then was less than one cent piece originally when introduced in the 1960s.
There was no big debate or opposition and no lobbying by coin producers or those who produced the metals. It just happened and basically everyone was happy not to deal with more pointless small change. And people still largely paid with cash too so electronic payment wasn’t as significant as it is today.
It shouldn’t be this hard.
