about $5/lb for plastic ic chips, ceramic ic chips, and ceramic eproms with no gold in the windows.
Eproms with gold bonding wires in the window (it's gold colored around the square in the window, or everything is gold in the window) are worth more than others. I don't have any value for these, but I think their gold content is at least 25% more than the previous group mentioned.
Eproms or ICs with gold plating on them and also gold legs are very valuable per lb, these go in their own category and sub categories maybe $75-100/lb?
This is just estimates
for value, but can give you an idea.
