I actually like the orange nickel. I'd just take away two of the extras colors. If me, I'd keep the green. But then you have the same green on the quarter. I'd drop that from 6 to four spots. keep the peach, and change the green to black. That would look cool with the black inlay.Maybe change the $1 or at least the colors. Maybe change the orange chip to a $20, $25 or $1 chip, but not sure if the red $5 and orange will be confused being close in color. The strips on the $5 not be to my liking when translating it to a card mold as in the strips are plain. That might be a deal breaker for me. Well it's just a start and trying to get other people's thoughts.
Then change the spot colors on the dollar to match the trees. Use the pink that I dropped off the quarter, then pick up the purple.
