Let's see. There are probably 5 or 6 different colors of each chip. I happen to get the same color for both, plus I know of no other colors of either. Second, the chips are probably 30 to 40 years old. One would expect plenty of wear. Neither chip shows wear.

When I say odd, I mean the chances of having the same color, both with no wear are quite slim. It is "odd" that these are the only two examples I have.

It is almost as if both chips were made at the same time from the same color mixture.
