Like filthy and mechanic said though, if you had a huge amount of one specific type they could probably run asseys and figure out the value of that specific type and possibly pay a little more but you'd have to have a ton of those to make it worthwhile.
I would also wonder if the non-precious metal weight of the boards has changed over time... perhaps the worthless material was a higher percentage of the weight back then, which could even out the gold recovered per dollar spent on boards.
I would take a guess on this and say yes. If you look at the older machines finger cards they had way more onboard finger IC chips. Them older boards have to have more PM content.
