Individually, I think the color-matched chips look outstanding. However, the red denom chips look more cohesive as a set. Imo, the black denoms are too 'bold' for the rest of the design... might work if the denom was a tad smaller, or the numerals were less dark (charcoal, for example). Hey, there's a thought! jk
I think if the individual chips were viewed side-by-side per denom, the color-matched chips would win hands-down. Looking at them grouped in sets, the natural inclination is to focus on the differences instead of each chip individually.
All that said, I think it's a toss-up between #1 and #3. All depends on which look you want to achieve. I'd probably go with #3, but it's very close. If I went with red, I'd probably take off the almost-too-bright edge a bit (ref. black comments above).
