here, http://mises.org/journals/qjae/pdf/qjae13_2_5.pdf, no less an expert than Mark Thornton in the Quarterly Journal of Austrian Economics, uses “intrinsic value” when discussing coins exactly as I described, both in the body of the article and in footnote 1.
in this article, http://mises.org/daily/4800, Rothbard uses the phrase the way I said. He was stating John Law’s ideas, and clearly disagrees with them.
this article was accepted for Mises daily, http://mises.org/daily/3039, and uses the phrase as I mentioned
here, http://mises.org/daily/3803, Mises himself discusses the concept I mentioned, although he calls it “industrial demand”.
Apparently “intrinsic value” is a very convenient phrase, and the users of it when discussing currency and fiat money assume some sophistication on the part of their audience, so that they will not be confused
