I think the grey/silver look best with the cash chips especially if $25s and $100s are on the table, then pink, then yellow. The color is about as subdued as the rest of the cash set; the pink and yellow are really eye grabbing. It's also related to both the $1 and $5 chips, with the white edgespots matching the base of the $1, and grey matching the edgespots on the $5s.
