I know some of the ribbon has gold and some have a shiney white metal on the ends, is the shiney silver looking is that silver? If it is silver who buys the scrap also I have a bigt pile of key boards any value?
Thank you

Nearly all ribbon cables end with some amount of gold plating on pin connection points. The part inside the plastic where the connection is made. The ‘silver’ you see through the tiny holes are the pin clamp connectors, they are usually tin or nickel.
Cables go as standard wire. Cut the ends off for connector ends.

Following this: "Cut the ends off for connector ends."
Just to verify: the plastic female connectors on a ribbon cable, including the inline ones, can go into the "Connector Ends" category? Please see the attached pic for reference. Thanks!

Yes

Those ends pop off pretty easy if you grab the side with pliers and twist in opposite direction.
