Hello everyone I want to ask something, my friend here sold an item that was worth 20m and what he got in return was two 10m book notes. Now how can he get those 10m book notes to turn into 20m cash? Because he wants to buy a pair of wings that cost about 15m but he doesn't know how to get his 20m cash since he got he two 10m book notes?b:bye

IIRC the banker has a quest that you can take to cash those in.
