Progression is really subjective, right? I don't care for how it works in this set, at least in the lower denoms that I'd use. I look at the quarter, the one, the five, and the twenty and it doesn't feel like a logical progression to me.
I love a few chips in this set - specifically the $20, $500, and $5,000 are all stunning. But taken as a whole, this set just feels a little too warm for me. Definitely an eyecatcher though.
