We also changed money while there. There are about 2500 Uzbek Sum per Euro. And 1000 Sum is the largest note. That means the largest piece of Uzbek paper you can get is worth 40 EUR cents. I changed 200 EUR and received 500 bank notes x 1000 Sum - thank god it was all 1000 sum notes. if it had been 500, 200 or 100 Sum notes i would have needed an extra pannier on the bike. Andrei here in the foto has just changed 20 USD.
