"In addition, since gold and silver regularly fluctuate in value, they could not easily
function as stable currency."

That is plain non-sense and probably disinformation.
It is the paper that fluctuates based on the faith that the holders have in it. The
fluctuations are based on the difference between gold and paper.
Most probably it is the precious metals that are the stable ones and paper IS still used
as currency, lol.

Another error ( Mr.Pitts?) in that post - It was not in 1930s but early 1920s that
Germany's mark was at the lowest. I think the monitory reform occured in 1922.
