The Susan B Anthony and Sacajawea dollars never caught on because they were foisted on the public for wokeness same. If Congress wants dollar coins to be used by the public, it should authorize the Ronald Reagan dollar.
The dollar is so dimly regarded as an amount of money, I don’t think a $1 US coin of any type would be successful. I just don’t think people want to haul around so much metal for a measly dollar, regardless of the design.
However, I believe a $5 coin could gain some traction. It couldn’t really contain any silver at that face value. A 40% Ike dollar (the ones not intended for circulation, they were sold in presentation packages) is about $7.50 in silver.
