Have had this conversation with lost and Boardsort. For reference:
viewtopic.php?f=3&t=19554&p=35735&hilit=Blanks#p35735viewtopic.php?f=4&t=19617&p=35966&hilit=Blanks#p35966Basically the blanks will all be low grade unless Chris sees something to know he can get something out of them. Or if you can find someone else set up to recover the material that's there, there is potential the boards are worth more than low grade. Also, gold is much higher than it was for those conversations so possibly worth the effort currently.
The box of random stuff. I see at least ICs, capacitors, pins, gold plated pins and ribbon cables. Not sure how Boardsort would but that but it won't be much because it's mixed.
Pins are likely brass with a nickel plating, or gold plating for those. There may be some steel pins if the manufacturer could get away with that, which would be troublesome as nickel is also magnetic.
Capacitors are likely aluminum.
ICs have their own category on the price list.
Ribbon cable probably just goes into low grade insulated wire.
