    The Narborough bone mill, with a big cast-iron wheel typical of industrial revolution water power, partially restored. It made calcium phosphate fertilizer out of bones from slaughterhouses, whaling, and, it was rumored, from a Hamburg cemetery:

    Among the gazillions of nearly random fertilizer experiments tried by British "improvers", presumably somebody tried this ground bone. It worked wonders, especially on hay meadows which fix nitrogen but deplete phosphate. Here's a bone crusher from Zurich canton in Switzerland.

    Haha yes let's look for written proof of how valuable the first gold artifacts were, at least a thousand years before writing was invented. :-)

    Yup. Typical traditional size was probably about like (L), only a little bigger than (and on Yap probably not much less scarce than) the jade bi disks of Neolithic China (R). For display or transfer carried on poles, akin to beads being carried on strings.

    Aztecs took gold tribute from their subject tribes. Spanish conquistadors looted the Aztecs. Sir Francis Drake looted Spanish galleons. Seizing gold vaults was a universal war objective. Many politicians have controlled monetary systems by controlling gold. Now we can do better.

    Fruits of fiat: dozens of episodes of savings-and-credit-destroying hyperinflation over the last century, including in Germany, Russia, and China. Currently there is severe inflation in Venezuela, Argentina, both Sudans, Iran, Yemen, and Turkmenistan. h/t

    The earliest copper objects were not weapons or tools for concrete practical use -- they were plug-in replacements for shell pendants and beads.

    Trust-minimized global money was the precious metal itself, not the form it took. Silver mined in the New World took various forms as it was traded and taken and spread around the world: ingots, coins, and wires among others.

    “Biblical descriptions of jewelry—earrings and bracelets—often include exact weights; the jewelry was deliberately molded into certain standard weights, so that it could be used as a means of exchange." Jewelry & ingots divided by iron chisel:

    Pre-coinage silver in action in the old Middle East: "And I bought the field at Anathoth from my cousin Hanamel, and weighed out the money to him, seventeen shekels of silver." (Jeremiah 32:9) "Weigh and deliver" in Mesopotamia:

    As New World silver from the Potosi and Zacatecas bonanzas spread around the world, it was transformed into a variety of different objects -- culturally distinct ways of storing, displaying (or hiding), and transferring the silver.

    We will look back on the idea that government bonds can be "risk-free" as a kind of collective insanity: "Despite history and facts, associating the word 'risk' with UST is for some reason blasphemous among financial professionals." ht

    For government bonds to be "risk-free", an investor would have to be a perfect fiscal prophet, for example an unerring predictor of who is going to win the next war. These bonds, among those of many other governments large and small, lost essentially all their value.
