Need help determining the price in USA

Hello guys! We mainly export e-waste from South East Asia to Europe, but today our partner in USA offered us 5 tons of, what I believe is, very high quality boards (pics below). When we offered him the price we would usually pay for these (10-12 Eur/Kg, or roughly 5.5-6 USD/lb) he said it's low and we should increase the price. How much are these worth in USA, roughly? Are we way off US price, or are we within reasonable range? Wild guess from our statistics, these are 300-400 Au per ton, so it's not easy for me to justify higher price, unless of course I'm missing something. Sorry if links are not clickable, every time I try to actually upload the picture, it wouldn't allow me, though copy paste should work. Thanks!

Your pics do not come up for me. I have only used Photo Bucket to download pictures to this site and you have to have at least ten posts before SMF will accept your pictures.

Oh shoot. I will reupload once I can, after I get 10 posts thanks

I can see the pics....the boards are what they are....$5 to $6 USD is more than fair....if you cant make a little money why bother...good luck and if they want more tell them to try and go elsewhere

Thanks! I thought maybe, for some weird reason these worth a lot more in US. For example, in SEA, computer motherboards are bloody expensive. Old ones are easily $5 per kilo, new ones are roughly $4 per kilo. At this price, I never send them to recycling plant in Europe, we always exchange or sell them locally.

Or for example, memory in US is a lot more expensive than in SEA and even Europe. I often buy memory for $15 per KILO, while US price, I believe, is often $15 per pound.
