Not at $20 each nubs.
Do you know a approximate yeild or fair price? He seems willing to negotiate.
In all honesty I don't nubs, I've always processed them with others as opposed to discretely but the yield would have to be ridiculously high per piece to account for your purchase price, time effort, materials and profit at $20.
What is a pop and what a nub?
It is "a pop" as in "$20 a pop" or $20 each. Nub could have several meanings as well. One such is when a finger is partially removed, the remaining piece is called "a nub". Used as a name, I have no idea. It is mainly a southern "thing" here in the U.S.
A pop is another way to say per so $20 per unit. And nubs is in reference to my username nubs16s.
I just collect them , not yet processed, but information says 286 CPU`s contain between 0.22-0.3 g of gold (may be speculated), therefore the gold value if you calculate with this yield would give you 0.22x94=20.68USD
There is no margin for profit with this purchase price, and if you calculate the time and chemicals you will end up in a big loss.
To be wort buying the maximum price IMHO is around 5-8 usd. so after recovery and refining you would end up with a small profit. You have to explain the seller why you are offering this price, by explaining the chemical cost, the time, refining and melting into a button.
But this is just one opinion.

Thank you for the information that helps alot. I'll reach out to him and see if I can get a deal to get his entire inventory for $5 a piece I know he has at least 20 of them.

I have 10 of them among many other Ceramic CPUs, but I haven't processed them yet. I have done some research, and I estimate about 0.06-0.1g/piece, or about 18g/kg for them. This is the lower yield estimate, with the possibility of them containing much more gold.
That's good to know. Can you share the weight of your 10 or just the weight of 1 so I can estimate the weight of the lot? I had previously seen .1 grams per cpu on old yield lists here but I believe they were from lists the community found to be bad and untrustworthy so I didn't to trust them. What are you using to get your estimate of .06-.1 gram per?

There are two types of i186/i286 microprocessors. Even though they have a very similar yield, one of them looks like the first image in the attachments weighing about 3.9g/pc, and the second type looks like the second image and weighs about 11g/pc. I used both Trinity Gold's (a Refiner YouTuber) estimate where they processed these CPUs, and I also used an article I found on a Russian blog website where many Ceramic CPUs gold yields were listed, and since almost every single yield per CPU was nearly dead on (on the lower range of the yield), I figured the gold yield their 0.07g/pc estimate per i186/i286 could also be accurate.

Amazing thank you so much. The lot I'm looking at is all the second type. If you are feeling generous would you be able to share a link to the Russian blog site so I can see the yeilds of others as well? I've been making a spreadsheet so I can more effectively buy material to avoid losses. Now I am curious where Goldman is getting his estimate of .22-.3 and which style if not both as that is quite the difference.

Sure, no problem. Do keep in mind that you will have to use a VPN with a Russian server to access the website, as the website doesn't allow foreign IPs to enter. Blog site is http://dzen.ru/a/X6e40UejSBLO14Hc
Interestingly I was able to load the blog with no problem without a VPN but when I tried to view the comments it would lockup and the page would go white. Maybe it's because I use brave browser or that I'm on mobile but I got what I need so I'll take it.
Sad news the seller responded to my message from yesterday looks like he received an offer of $300 for the cpus so that's a no go.
He did show me some other scrap he has on hand and had a great conversation about refining. The man has survived 3 nitric acid explosions.
He's got a 1982 data general mini system for $150 which I think I'm gonna pick up, 383 grams of gold plated pins from a different data general mini system for another $150, and 532g of ibm palladium pins from the 60s for $50.
I think I'm gonna buy the data system and palladium pins but it's time to go dig through the forum and look for yield data
Edited to add he just sent me the XRF results of the palladium pins which shows 2.21% Pd content. So 532g X .0221 = 11.7572 grams of Pd with a spot price of $31.25 for a total of $367.41 quite the deal for $50 I can only hope the gold pins are of a similar content

I would guess that the buyer who’s paying 300$ is probably purchasing for collective purposes. Best of luck to you with the pins, be safe!
That yield comes from a list I found when i have joined this hobby. (I do not claim it is correct, , for purchasing i use as guidence)
I accept if yields are lower, but 0.06g is approximatly AMD ceramic with aluminum heatsink (according to my list) which is way newer (1997) than the 186/286 (which is from 1984-85). I suspect it should have more gold in it than 0.06g.
At the end of the day you have to draw your own conclusions.
Pete.
