Interesting read. I've never read much about the gold standard but this is some good perspective.
Based on this article I can see the advantages of owning gold or silver as they are convertible into any currency, but I don't see the advantage of tying the value of a given currency to it. It may limit a central banks ability to unfavorably manipulate the money supply, but it also limits favorable manipulation such as during an economic downturn.
The part I'm curious about is the article discusses the effects of a gold standard with the continuing use of central banking, whereas I know most of the proponents of the gold standard are also proponents of removing the central bank(s). They do make the case that the gold standard does not stop price volatility with the use of a central bank, but they don't discuss much if it were to be removed in conjunction with a reintroduction of the gold standard.
The Federal Reserve bank was created in 1913 and their data seems to stop at 1914. Based on their chart I see the price of gold in nominal U.S. Dollars as pretty stagnant from 1914 up until the 1930s when the Federal Reserve's powers were significantly increased during the depression. Of course, the chart also shows a good bit more volatility in the price of gold in inflation adjusted dollars throughout the spectrum and then increasing in volatility leading up to the end of the gold standard. It might be interesting to analyze that chart a bit more closely adding in milestone markers for changes in power/policy in the central banking system.
