Best way to sell C4040 and grey trace C4004

[willsmith]

I have a couple of C4040 and several C4004 I would like to sell, including a grey trace.

I appreciate the C4040s are very rare these days, and almost never come up for auction so I will be taking these auctions carefully to make sure everybody who is interested is aware.

Also a number of related chips : C8080A, C8008, C8008-1, C2102, C3101, C3002 (ES and normal), C3003, C4002-1, C1101, several C1103 (first ever DRAM, took me years of looking for these).

I bought all these around the 2001-2006 timeframe , in many cases I recorded the original Ebay auction as "provenance" so you can see who I bought from and at what price. Even back in 2005 I paid $200-$500 for the 4040s and 4004s.

What's the best way to sell these? Ebay or direct here (but with the high values of the C4040/4004 maybe best to do ebay?) Any tips to avoid bad transactions? I haven't sold anything very small and high value on ebay for a long time.

I have these mounted all together in a few cases in my home, I guess I should buy some more cases to be able to send them individually?

Also, back when I bought, there were no testers, so I'm not sure if they all work. Do people care these days?

Please reply if you have specific requirements and want to be notified once I list on ebay.

I can offer testing services for 4004/4040 3002 8008 and 8080s if needed

Looking forward to your sales.
Please notice the first time.
In addition, I am currently making a boutique chip protection display box.
It may help your sales.
The approximate price is $3 each, not including shipping.
If you are interested, I will make a DIP protection display box for you as soon as possible.
The figures are two examples that have been made.

Hello,

Do you have Intel C4002-2 grey trace for sales?

It's fairly important for such expensive chips that they are guaranteed to work. Not so much because people will use them, but a chip that works definitely isn't fake. No one wants to spend $1,000 on a CPU that's just a remarked $1 RAM chip. If you were to sell them here, CPUShack also does escrow for these sort of bigger deals. The buyer would send the money and you would send the chip to him. Once it's tested he would forward the chip to the buyer and the money to you (minus his fee). That way there would be less handling, and less postage for you to deal with to have them tested. It would remove a lot of risk for you too in terms of fraud on these bigger deals.

That's interesting. I'm thinking about a PDF test report (at all testing frequencies w/ power consumption report and benchmark) that could be generated after testing with the UCA.

I also would be interested in these display boxes for my rarer chips.
Small and large sizes would be great a idea!
How about one for the MCS-4 set?
