IBM 5170 piggybacked/stacked RAM Chips

[marminsky]

Hi, I found a number of RAM chips (over 30) in a piggybacked/stacked configuration, on some of them you can still read the model: OKI M37S64.
I also attach a photo of one of them.
From the minuszerodegrees website (http://www.minuszerodegrees.net/5170/motherboard/5170_motherboard_revisions.htm) they should correspond to the DRAM chips installed in the first version of the Motherboard of 5170 "Type 1".
In your opinion, could they have a market value? Keep in mind that I don't have a chance to test them. Thank you.

When I needed some, I went here: http://www.minuszerodegrees.net/memory/41128.htm
And I searched eBay for each tested part number, and I found some NOS chips still in the tubes for reasonable prices. Shipping to or from some parts of the world might be show stopper, so you might be able to get a decent price for them if you sell them locally since I assume shipping within the EU might be cheaper for you than for someone on a different continent.

Thanks Jafir for your answer, indeed overseas shipping costs can be high.
Just out of curiosity, Can you tell me how much you paid for those chips you bought (excl. Shipping costs)?
Thanks again.

These were Samsung, which in the 1980s and 1990s was not considered a good brand like they are today. They were being sold in lots of 8, and it looks like they were about $7 per lot, so less than $1 each. This was in late 2018, so I'd look around on ebay and see how many there are out there right now and go from there. I'd expect the prices go up and down based on when someone finds some hidden away in a closet

I'll bet you could get at least a couple of euro each for them.
