I don't think the fact that it was saved before the Hindenburg explosion adds too much, if not anything at all. I'm not sure about everything else.
On the off-hand, I have a few mexican pesos from 1945.Another one, worth 100 pesos, is from 1977 and marked "plata pura". (Pure Platinum)It's silver, shiny, and really really valuable :o
