Mega,
I have yield data on many of the types of scrap that you have posted photos of.
The problem is that each type of scrap is different in little ways (plating thickness, full or partial plating, trash in with the scrap, double side vs. single sided, etc.) so the variables all have to be considered when making a purchase and yield estimate.
The fingers you have appear to be double side and fully fingered (all the connections are filled with no missing sections), but they also appear to be on thicker and wider boards than usual as compared to standard pc card material. These fingers would fall into a group that I call mid-high grade and would yield between 1.5 to 2.5 grams of 24 kt Au per pound ballpark.
If they were trimmed better and on narrow thinner card stock they would easily qualify as high grade (2.5 to 3 grams Au per pound) finger scrap. If they were from older (25+ years) equipment they may reach the ultra-high grade at 3+ grams per pound.
It's important to realize that by trimming the excess board material the bulk weight will decrease and the yield per pound will increase proportionally. Always remember GIGO; Garbage in = Garbage out.
