I alway think of this when that sort of question comes up.
I was stationed in the Azores, 1979/80. The currency was the Portuguese Escudo. On base we still used Dollars at the PX and Commissary. A heavy-set rough-cut guy (mobster?) nicknamed Tony the Scoot man, stopped almost every day at every duty station on base and offered to swap for Dollars on an even exchange rate if anyone need Escudos to pay rent off base, eat dinner at a restaurant, or even just to go shopping in Praia da Vitória, the little town near the base. Tony would box up the dollars and send them to mainland Portugal where his cohorts would convert them for a better exchange rate back into Escudos. If that is not a money launder's dream...
All this woman had to do would be to go back to Turkey and sell the loot in bulk for Turkish lira. Then it's up to the person she sold it to, to worry about putting the money back into circulation.
