I went to the Four Winds Casino web site
www.fourwindscasino.com and they show what looks like their $100 chip on their home page. Here is a scan of that chip. My parents live 20 miles north in Saint Joseph. This casino has apparently hired over 1000 workers from the local area and is considered to be a boom for their local economy. I should be able to visit there next year when I go visit my folks.
