I've been working through several old computer and industrial machinery (late 70's early 80's). I've noticed the paths on the circuit board are much much larger than what I normally see - between a quarter and a third of an inch wide, and they are on top of the board. Several of these appear to be silver. Now I have a pound or two of boards with nothing of signifigant value except the silver on them. Some have small resistors or a few small capacitors, but for the most part these are empty boards. I will check with my normal buyer (EWasted), but I wanted to see if anyone had any experience with these. Am I correct this is likely silver plating on the old boards? Are they anything better than low grade for anyone?
