I am especially interested in learning what kind of metal is in those spring loaded gold pins net to the quarter. What else do I have here?

1) as is peripheral
2) if you're pointing to the red adaptor its nickel most likely
3) both telco. You can remove the socketed gold pin IC chips. Ones with the window are 486 class. Ones without the windows are pentium ceramic
4)
The spring pins are called exactly that. Spring pins.
Contact pin: They're usually a gold mil on nickel, with a thin steel core.
Rod sheath is often a k-class stainless steel. Aka A non standard blend of steel and nickel with other elements.
Drop one a bit of distance on concrete, if it clangs it's a 400 series high speed stainless. If it 'rings' like a tiny bell it's a k-class.
The spring itself is usually tungsten. I wouldn't suggest snipping them to get the spring out. Judging on the look of a few you may have already learned the spring is under a considerable pressure despite the small confines and loosing all three pieces is quite common.
You can email Chris directly; top left of home page, and let home know and send them in. They scan them and pay out based one he actual weight of the various metals.
No one has told me exactly but my calculations put the gold payout rate between 87-92% of clean commodities rate: almost 6 times higher than most cash for gold places.
If you're brave enough and/or inventive enough you can snip a pin and try to catch the spring.
If you do that on even one you can take all the separate pieces to most higher end jewelry shops and beg them to scan the parts giving you exact knowledge on what ratios you have.
Clean tungsten runs around $14 a pound so that route may be advisable if you have enough of these.

Flip the IC in last picture over for classification.

Where did the pins come from. They're long enough, almost, to be punch card pins.

#1 does that mean I can clean board #1 enough to get telecom price?
#2. I was not pointing. I was thinking about the date on the board. Thanks for the info on the gold chips and spring pins. I have a device with about 60 boards of pic #1. I also have an old device with many boards populated with many small relays and Ic chips. Should I take a pic? What about gold plated relays? What about slightly magnetic contacts from car gas tank sending units? I know I sound needy. I am just learning. Thanks. Knowledge is power.

I do not desire to take these spring pins apart. I have many. What are they worth per pound?

i pulled the spring pins from a few devices marked as Kodak. Some of them come from a telecom system of unknown origin. I have over 500 pounds of boards. These boards are connected to a few nice long backplates. All from the late 70's. I have gold pins for days. long ones. I need as much info as I can get.

1) actually I was referring to the need to not cut the fingers off; as it would then go midgrade

2) I'd need a full board picture , but my guess is a 79 or 1980 base module motherboard from what I can gather from the few ICs and patent date. Large socket or telco if I'm right; but post a full photo I can tell you for sure.

The spring pins aren't all that dangerous (beyond your eyes and the tummy of pets and small children)as much as finding the parts after they take flight is a pain. But with your volume it's not a worthwhile endeavour
There's no way to tell you what they're worth till they're scanned. But they start at $1/lb for plated steel and $5/lb for plated nickel, and go up from there.
Old military equipment and telecommunications pins; tend to be under $5 per pound, or over $10
Anything beyond that is guessing blind.

Yes, post as many pictures as you'd like answers for.
Relays, if you pull the metal piece out you can have them scanned and quoted same as gold pins.
If you leave them in the plastic your looking at a random price depending on yard. Boardsort doesn't buy them. But ranges are $1-$5 per lb whole
When you fill out your order and get a number just shoot an email to Chris and let him know your also sending in pins/plate for a quote.

The relay sensor for automobiles; often chromium plated, lead or zinc under the plate. Not always though, and much newer cars tend to use a chromed ceramic or even chromed plastic. Assuming we're thinking the same, we, bob sensor.

2) Is the second photo and the first board on the left. It is marked Intel 1977 mathematics processor. This unit is full of Ic chips and a few gold chips.

I have been under the impression, Gas tank sending units use palladium because of the inert corrosion abilities opposed to silver. Is magnet testing these things useless? :(

Some higher end modern vehicles and many older ones 70s/80s may have palladium which is nonferrous, not magnetic. If it sticks it's usually chrome, which is magnetic
