The 3 large boards are from a traffic signal circa 1970s. The red ceramic capacitors are heavy and non-magnetic, ergo they contain palladium. The buttons have heavily gold plated contacts (see pic).

The wide assortment of IC chips:

All have gold legs (there are 3 with silver plated legs).

The chips are made of ceramic/epoxy, all epoxy, epoxy/metal, or some combination.

And everything else shown in the pictures. These are chips with the highest gold content - I estimate 8 to 10 grams of gold, minimum (this is not a guarantee, it could be higher). These are extraordinarily rare chips, the likes of which you have never seen before. So rare, it\'s almost impossible to find any information about them on the web. The traces on the circuit cards are likely plated with palladium, given the color and the age of the boards.

Shipping includes insurance and secure packaging. Signature required upon delivery. There are no returns on this item, this is sold AS-IS. You are still covered by \'s money back guarantee. What you see is what you get. In the event of a discrepancy, the pictures are the ultimate authority.

Thank you!
