A second confiscation took place in 1982, when the ₵50 note (the highest denomination) was demonetized. Ghanaians, in theory, could exchange any number of ₵50 notes for coins or other banknotes without loss, but foreigners could not make any exchange. However, many Ghanaians who were hoarding large amounts of cedis feared reprisal if they tried to convert all of it, and so simply burned a lot of their money. Many other Ghanaians received "promise payment notes" from the banks, but never received compensation. This confiscation was publicly justified as a means to create a disincentive for the flourishing black market. However, from a monetary perspective, currency confiscations have the effect of reducing the available cash in the economy, and thereby slowing the rate of inflation. After the ₵50 note confiscation, the ₵20 note was the highest cedi denomination, but had a street value of only about $0.35 (U.S.)
