  I'd say they are more similar to the Guano Era[1]. A highly sought-after resource which becomes irrelevant once better/cheaper alternatives are found. [1] https://en.wikipedia.org/wiki/Guano_Era https://en.wikipedia.org/wiki/Guano_Era

  Well for a start half those dead currencies were replaced with new currencies issued by a different authority and their holders compensated, often at parity. As for the ones that collapsed, they tended to involve dictators and wars rather than people simply deciding they weren't worth wasting time on because nobody was interested in exchanging them.

    > Well for a start half those dead currencies were replaced with new currencies issued by a different authority and their holders compensated, often at parity. Indeed, I see on that list the several Brazilian Cruzeiro/Cruzado currencies. The only difference between each of these and their predecessor is that three zeros were cut: if you had 1000 of the old currency, you had 1 of the new currency. The last of these was replaced by the current currency (Real) at a slightly different rate (2750 instead of 1000). That is, it was more like a renaming than the currency actually dying and being replaced. And there was no different authority in these cases, they were all issued by the same central bank.
