Is there a legal tender silver or gold coin dedicated to Chicago? The closest thing in the Red Book and Google is the 1892-1893 Columbian Expo coin which only has the word Chicago in it, but it's not really dedicated to the city (e.g. its founding). Even Elgin, IL has its own commemorative half dollar... And, I know that the silver 2003 S Illinois state quarter has the city of Chicago as part of its design, but it's not dedicated to the city. And, there are some exonumia, but that's not legal tender... Just thought I'd give it a try and see if there is one, but then again, not even NYC, LA, Boston, etc. have one. Thanks in advance!
