I honestly can't say the age of the boards I have collected thus far. Some were from older electronics and some from newer. Basically... I scratch the solder masks of any board I get that I think may have gold underneath and if I see a yellowish shiny vs the more common pinkish copper... I want to try and recover unless the board is very small and super dense with populated components. But some boards have visible plating or flashing, with copper under the mask, but can't easily be cut out or has components soldered onto the gold so I'd like to depopulate and de-solder.
