Great collectible for your vintage collection. 

Chips are in good condition, 30 plus years old. :)

So many of these have been destroyed by the gold scrapers , it is a shame for the history of these unique technological items to be lost forever. 

So save a piece of history and a good investment

 as the gold in these chips will always be going up. :)
