MC2833, MC3356p, MC2833P semiconductors

Okay, got something today I've never seen before. Wondering if anyone here has some info on the plates that I found in the bag with these ic chips. The chips appear to be new and unused. All of these items were inside of a plastic bag in a lot I got from a computer engineer's place.

I've seen ic chips before and know they are roughly $5 a # as is, but wondered if there was anything special about these specific ones, together as a lot, and along with these plates.

The plates seem to be some sort of circuit map? But I really don't know what goes on inside an ic chip. Does anyone know if this lot has collectible value as is, or if these plates are special in some way? The shiny ones appear to be aluminum on time of white computer board backing. The smaller boards are on the older style motherboard boards, but not sure what the trace is made of.. Any help or info appreciated. Thanks!

and sorry my phone takes crappy pictures. saving up for a nice nikon in a few months...

these say mc3356p xhaa9305

Nothing of collector value that I see.

okay thanks. do you know what the metal plates are? Some kind of schematic??

Might be the master of the circuit board the chip's mount to.

Just checked E-bay. They aren't selling.....at all.

Might try selling to an electronics surplus company beings that they are new in the packages.
Might be someone here that you can check out; buyer of surplus... - Search

About anything they offer would be profit.
