I have some small boards that don’t have much on them. The ones all in one picture come from irrigation timer modules and have large gold contact pins but not much else. On boards 2 and 3there really is almost nothing as far as components, but the board itself has a lot of gold showing, my question is how much does this gold (flashing maybe?) on the board vs in the components help the value? Is there as much gold as there appears to be? I’m assuming there is not. And how would these be graded. Thanks to any one who takes the time and answer and teach me something.
