I read something very thought-provoking recently and wanted to throw this out there for comment. Basically, the author (I think it was a survival blog site) said that frequently when currency is revalued it only affects currency, not coins. In other words, assume we are told that there is a brand new U.S. currency and one new $1 bill will be equal to a current $100 bill effective immediately. So a $100,000 bank account or cash you have on hand as a rainy day slush fund goes down 99% overnight. But this author basically said that often times the government doesn't want to mess around with pocket change (coins). So a single nickel you have in your pocket would be worth $5.00 (or perhaps even $50 if three zeros are dropped from the currency) overnight.
First, can anyone give any information (including links if possible) indicating how this was handled with currency devaluations since perhaps World War II? Any information about what happened in Zimbabwe, Mexico, Argentina or Yugoslavia would be nice.
And what about brokerage accounts where you have stocks, mutual funds, bonds and cash? I assume that the cash would be devalued immediately, but it is hard to imagine Apple stock suddenly being worth only 1/100 what it was yesterday. After all, they're still gonna sell a lot of iPhones.
What comments can anyone share on this matter?
