I have a PRISTINE example of this R-8 chip for sale. The scan shows both sides of the chip. The cross-hatching goes all the way to the edge. The gold hot stamp is very good on both side; the scan doesn't really show this.

This is an excellent sample of this chip. Campiglia & Wells show it as $150 - $300 - $450.
The first $300 gets it shipped to your house insured!

Thanks,
