You don't even need to look at other countries, when the US discontinued the half penny it was worth more than modern nickels are worth

It's ridiculous that anyone is saying anything but fuck this traitor for issuing unconstitutional orders over and over again.

What’s unconstitutional about it?

The authority over U.S. coinage is established in the Constitution (Article I, Section 8), which gives Congress the power "to coin Money, regulate the Value thereof." Any major changes to U.S. currency, including eliminating a denomination, must go through Congress.

>“The Secretary of the Treasury shall,” Section 5111 reads, “mint and issue” denominations of coins “in amounts the Secretary decides are necessary to meet the needs of the United States.”

I agree with your sentiment, but according to another comment in this thread, the treasury secretary has congressionally approved latitude to adjust how many coins are minted.
