 |

Hi
I received these offer for refining but I am interested in knowing their values as vintage, please kindly advise their estimate collector values.
Thanks[/b] |

the DX2-80s if decent pins, are $10-15 each (more then gold value by a fair amount)
The Cyrix MediaGX is probably $8-10, also higher then gold
the rest without better pics are probably scrap quality

| Thank you. I assume selling them on eBay would yield even higher than those ranges you mentioned? |

| You could probably get $40 or so for all of it if you wanted to sell all of it to one buyer as a lot. |

Have you ever recovered gold or just something you read about?
A pound of 486 or 386 sell for $200 sometimes cheaper but people have better luck with just listing how many instead of weight and can fetch $300 plus a pound especially buy it now auctions.
On average 486 CPUs with gold caps yield .20 to .22 of a gram per cpu. So around 5 for 1 gram give or take on model and where they were manufactured. That comes out to $12 per cpu in gold. Sometimes a little more others a little less. You start to learn yields when yield gold from only one model by doing 10 at a time and getting a average.
I can tell you yields for everything of course besides for chips that are worth a lot, rare or samples but even than I could ask someone in the refinning community. 99% of the refiners have no clue about hardware especially what should be saved.
I have almost 12 years of experience recovering and refining precious metals from ewaste, jewelry and electrical equipment like breakers, relays and so on. I had to stop due to being diagnosed with a rare disease. Had nothing to do with the chemicals, just bad luck.
I dont support this guy because hes uses no common sense but he uploaded a video last week refining 250 KILOS of ceramic CPUs, 900ish grams of gold recovered on youtube |

Note: None of what he posted in the picture has a gold back, all are ceramic die covers (including the 486s)

I know that. I was trying to let you know that other CPUs do have that much gold and none gold cap 486 chips only yield a little less but you made it seem like most cpus have very little gold.
The Dx2-80 sold recently for $35 as a gold scrap auction, only one but im sure someone wanted it for collection.
A lot of the information you find on the internet is just wrong and highly inflated. The best guess for that is its a con. Someone or several people figured out they could sell material for much more than precious metal yield if they spammed false yield data around the web. Dont have to waste time refining and you save a lot of money on acids even though new techniques have been invented like Eco GoldEX which dissolves gold without having to dissolve the base metals, AR does dissolve gold but its a endless cycle with dissolving the gold than cementing out on the base metals untill they are fully consumed. |
