For anyone who's dreamed of life without coins, my answer is: try having a wallet stuffed with a wad of low-value paper money. Bottled water is 250-500 dinars ($0.22-0.43), and once you've gotten a few 250 dinar bills you realize the jingle of coins is a rather nice sensation. Pennies, i will agree, are useless for the most part. In Turkiye the smallest coin is 5 kuruş, and that's a nice stopping point.
Regarding prices here: good quality men's dress shirts in the bazaar start at 10,000 to 15,000 ($8.50 and up). Regular gas 750/litre ($2.40/gallon), and Marlboros cost about $1.40 a pack. Decent fast food can be had for less than two dollars. So come to Kurdistan - but remember to bring a wad of cash; when i find (glory be!) a seller with New Balance sneakers to replace the tattered shoes i'm wearing, i discover merchants are not set up for plastic.
