Hi Jill,
I'll bring 2 C&J hotstamped chips to show you at the convention --
50c Carver House
50c Las Vegas Club Pan (same era as yours if it is a C&J)

You'll see the difference immediately. The hat reflects enough light that you could use it as a mirror to signal airplanes if stranded in the desert! (Well, I exaggerate a bit on that one. )

Just look me up at the banquet or the bourse floor. I don't have a table, but ask and someone will point me out.
