Who refused to support a policy of soft silver money?

Question

i am looking for a specific name.

Answer 1

In the past 30 years, pretty much everyone. There is no rationale to limiting the supply of money based upon the amount of mineral in the ground.

Prior to that, it was a viable political issue, especially in the late 1800s when the gold standard was felt to be inadequate for monetary stability.

***** EDIT *****

Now I see the "soft" - meaning silver certificates, which were issued for a very brief period in the 1930s through 1950s when the US left the gold standard after the Great Depression and entered a silver standard. If you pull up the Congressional Record from 1963, you can see which senators and reps voted for fiat currency, which ended the silver certificates.
