I brought them all in to work this morning and here is the scan:

You can see that the Royal chip is a third color, more yellow than either of the other two varieties. The missing inlay chip is an oddity, and no doubt one of a kind (although I doubt it has any value whatsoever). I don't consider it a variety, but keep it just for fun.

I would be interested to know if David Spragg thinks this chip was made incorrectly or lost its inlay somehow.
