Good luck. When I tried to exchange a few coins from Canada at O'Hare a few years ago, the made a face like I was holding a pile of dog doo and said they didn't do coins.
I believe some downtown banks have a currency exchange.
Thats the thing i went to my bank and countless others and all have suggested international airports, also called a few airports such as this one and they recommended me to the bmo harris bank inside general Mitchell airport, called the bank to and the lady said "no one does foreign coin currency exchange" im stuck on what to do
Take it to your bank, you will get better rates. Or worst case Craigslist or ebay
Most international airports have a currency exchange.
