I have had these for a little while and now it is time to let someone else enjoy them. Book value is $100 each in very good condition and $200 in new condition. I don't think these are quite in very good condition. Easily readable but the hot stamp is gone. These are in used condition. You can have both chips and if you look you will see they have reversed inserts.

Both chips are only $50 delivered - and I have a few pairs available
