List of 590+ Dead Currencies

This list of 590+ dead currencies is interesting.   I think there are nearly 150 listed as "hyperinflation".   I expect that many of the others listed as "war" would count as hyperinflation if we used a 26% yearly rate as the cutoff.   When a war is going poorly the currency usually is going poorly as well.  So while it is reasonable to list war as the reason the currency died, the currency probably hit the 26% inflation mark before it died.

Note that ounces of pure silver or ounces of pure gold will never completely fail to have value.
