Lop is just a figurative term. The dinar you have now would not change one bit. The rate would stay the same. They issue a new currency, smaller bills. Those have a new rate… 85 cents… maybe they make it 1:1, a nice little increase. Both currencies exist side by side for how ever long the exchange period is… anywhere from a month to a year. After that exchange period the dinar you hold now becomes worthless… just like the old Saddem dinar now. The exchange of old for new is 1000 old for 1 new… that’s where the term 3 zero lop comes from. It’s just figurative though.
They "CAN" just drop those zero's with out printing new currency. That is what the difference is here. No one know what they will do. The lowest Inflation rate for a Country that has lopped had a 125%.
