content: I was just looking around on eBay and found thishttp://www.ebay.com/itm/65-LBS-Of-Computer-Circuit-Board-Scrap-for-Gold-Recovery-/221051669064?pt=LH_DefaultDomain_0&hash=item3377b4ca48How much gold could you seriously get out of 65 pounds of junk board? I remember seeing a video on a tech site (can't remember whether it was extremetech or tomshardware) that you can only recover a tenth of a gram of gold from a single motherboard...

content: At ~$50AUD per gram, you'd want at least 6 grams of gold to break even, and that doesn't include tools, consumables, and effort put in to extract it...You can't blame the seller, he didn't set the price. Not completely his fault if people bid too much on his useless junkTo be fair, he never claims how much gold is actually there to be reclaimed.Also, the layer of gold on these things is ridiculously thin. It's only there as a contact surface so won't be more than a few microns or something thick.

content: Buying old boards is more than just gold, the big haul are the rare elements in some components, once extracted from slag. This is why I posted on another thread, the interest is this process has made recycling PCB more earth friendly in developed nations, given that China, a large source of such, threatens to control its distribution.http://en.wikipedia.org/wiki/Rare_earth_element#RecyclingHow much its worth:http://www.cnbc.com/id/42194545/Rare_Earth_Metals_Become_Recycling_Gold_For_Cleantech_Sector

content: last year I remember seeing a similar auction.. it was for a box of junk PC boards, like this one. it was sold at around $800 USD.I couldn't believe it! I think it was like 250 lbs of boardsit made me upset that I had just recently finished cleaning up and I discarded about 100 lbs of old boards myself.I sent them to the scrap bin. I was tired of seeing that old box of junk in the corner..
