Problem 1: too poor to miss out on few more pennies, ie, sell at a lower grade.
Problem 2: too old to spend a large portion of my remaining life trying to garner a few more pennies by time-consuming labor that isn't overly profitable.

Back in the late 80's I bought a couple pickup truck loads of vintage telephone switching stuff. Included were these wired card slots, screwed onto an aluminum cut-out frame. Nothing complicated: plastic slots with pins for receiving a simple card, well spaced apart gold fingers on a card with solder traces connecting finger to solder point for the telephone cable wires. Card holders appear to be nylon: impossible to beat them loose without removing the nylon screw. The unit as show weighs about twenty five pounds, and is roughly twenty inches square.
There is some gold flash on the connectors where the cards gold finger contact it. The overall pin itself is about two and a half inches, wire wrapped on the back, is oxidized to a light hazelnut brown, and appears to be a white metal, rather stiff, but breakable with about six deep bends. Non-magnetic.
Early next week, I intend to take some of the pins to my local yard for RFA?, shoot them with the gun, to determine composition.
Basically, what I have after removing the cards from the slots, is connector ends mounted on an aluminum frame. Wiring on back wire wrapped pins appears to be tinned or silvered copper (dark oxidation on bare wire, silvery soft moon like on fresh stripped)
Question apparent is do I need to remove the "connector ends" from the aluminum frame. Of course, the back wiring and cards and nylon supports must be removed. No board at all in this setup.

I’m confused:

Assuming the pins are part of the the same board as the card sockets:
How I would go about this depends on the pin composition.
If the pins are gold, wire wrap pin board is the best rate so remove cards and wires.

If the pins aren’t gold I’d pull all wire and sell the board with cards in for high telco.

But…

If the pin board and card boards are separate boards…

Well, I’d remove the cards, knock the plastic off the board and take high peripheral for the aluminium and card sockets.

But with big sockets like that: personally, I’m most likely to yank!
Remove the sockets. Smash them. Sell the socket pins, clean the aluminium, and toss the plastic in my #7 bin (other) for $0.005 per pound.
But that’s me.

Thanks Lost, but you missed the point that there is no "board." Just a bunch of sockets hanging on a metal cutout frame. Pins while large have only a minimum of gold flash at the contact points where the cards insert. I will post some comparisons of socket plastic weight vs removed pin weight on a couple sockets and show closeups of the cards and closeup photo of the pins.

I understood that the “board” was as thick sheet of aluminium.
What I am confused on is if the pins and card sockets are on the same piece.
