Well, I'm still playing catch-up from the past 2 - 3 weeks of intense events. I am not sure if this set has been shown before, but I was glad to get it.

Here is a composite scan of a sample set of chips from Chipco. This is a set of 6, stacking chips. The common back is shown at the bottom of the scan, next to a scan of the image revealed when the 6 chips are stacked.

Thanks for looking,

Jim
