Don’t get too excited. The RES-1 is in lousy condition. Note the big edge nick at 12 o’clock on the bottom image. Edge chunk is probably a better description. Still… clean it up and display the other side & it may be a filler chip for a new collector. And when was the last time you saw an RES-1 for three bucks! $15 for the lot. I'll pay the postage in the USA.

First email gets the lot.

This is my last AC chip offering for a while. Promise.
