According to a study of 775 fiat currencies by DollarDaze.org, there is no historical precedence for a fiat currency that has succeeded in holding its value. Twenty percent failed through hyperinflation, 21% were destroyed by war, 12% destroyed by independence, 24% were monetarily reformed, and 23% are still in circulation approaching one of the other outcomes.

The average life expectancy for a fiat currency is 27 years, with the shortest life span being one month. Founded in 1694, the British pound Sterling is the oldest fiat currency in existence. At a ripe old age of 317 years it must be considered a highly successful fiat currency. However, success is relative. The British pound was defined as 12 ounces of silver, so it’s worth less than 1/200 or 0.5% of its original value. In other words, the most successful long standing currency in existence has lost 99.5% of its value.
