Why not keep the $1 (the workhorse chip in your cash set) representing Michigan and completely change the quarter.
Then, make the $100 or the $1000 (the workhorse chip in the tourney set) also be the blue and gold to represent Michigan.
As it stands now, you have 2 chips together (quarter and dollar) that could cause problems, and you have no Michigan chip in your tourney set.
This is a pretty good idea.
Or my thoughts, the T1000 chip becomes the workhorse and makes up most of the tournament stack in a T10K event. why not just make Michigan the T1000 chip and stick with
yellow maize? And then you can even just do a generic "B1G" logo on a Pink T5000 (so you don't have to put another school on higher value), the Gophers probably deserve to be a quarter, so you could do a gold quarter with maroon spots, stick with #TeamBlueDollar for the cash chip for Michigan.
So if I may remake the whole lineup.
0.25 - Gold/Maroon (Minnesota)
1 - Blue/Maize (Michigan)
5 - Red/White (Indiana or fun idea, get inlays for Indiana, Wisconsin, Nebraska, Rutgers and divide them evenly across all red/white chips)
25 - Green/White (gulp, Michigan State, but at least it's the bottom of the tournament set)
100 - Black/Yellow (Iowa or maybe a Black and Red Maryland is better?)
500 - Purple (Northwestern)
1000 - Maize/Blue (Michigan)
5000 - Pink (Generic B1G Ten)
So this way Michigan gets the two most prominent spots in your set. I think you get around all dirty stack issues, Ohio State is noticeably absent which I think is a great feature as well.
