I need some help with some stuff I came across. I have about 10 pounds of them. They're known by "military pins" manufactured by "ITT CANNON". The model/sku is M39029/32-259. From what I've read they're 50 micro inches plated. A couple of people I've given samples too said 1-3% recovery. Can anyone shed some light on this?

When I google that number everything says Amphenol not Cannon. Some pictures would have been helpful, here are a couple I found based off that search if these do indeed match what you have? The pictures appear to show good quality pins however you also didn't say if they're male or female? All the pictures of the female pins which came up show stainless steel sleeves, which would prevent processing them in a cell unless you physically or chemically removed those sleeves first.

1% would yield about 4.5g/lb. They will not even come close to that yield. You can get .75-1.1g /lb on those.
You have everything you need to find out by your self. Just calculate the surface area, then multiply it with plating thickness and the density of gold. That would give you the amount of gold per pin, then use a scale to find the weight per pin and you can calculate the percentage.
