How much are old broadband cards/aircards worth in scrap value?

I won an auction for about 80lbs of the things, since they're only compatible with a PC slot, there's no real market for them as functioning units, but they have a lot of gold plating (not even fingers, the whole port is plated with gold), so I was hoping I could do maybe a little better than cell phone scrap price on these. Any help is really appreciated.

Thanks thortek, that's more or less what I was thinking.
