No, a PERFECT progression would be top row 5, 25, 1000, 100, 500.I like the 1st one best. The progression is perfect.
Why not simply take two or three versions of the $1k? This is your highest denom, so you probably won't need too many of them. 25? 50?
Grey/White/Red is a great-looking color combo which also goes very will with black ($100) and purple ($500). Because of this I will order the regular $1k chip. But I will also add a secondary $1k to my set, either orange or yellow, so I can always play with the $1k chip that I'm in the mood for.
