Hi Pete. I could have answered this a long time ago, but I liked seeing my name appear so many times, I waited. I guess they're finished now.

Both of your chips are the "Large $1" where the $ is deep into the red. The "Small $1" is barely into the red & is N7698. Both of yours are N4773. You are right about the different colors of the chip, in fact I have 3 different colors. Each time a new order is run, the shade comes out a little different. If we listed every shade of beige, gray or blue as a variation, we would need a hand truck to carry around The Chip Rack. Some people like myself, collect all the variations, but we see no real need to list them all.
