I pulled these out of a tv, are these solid gold or plated? Scratched them and all I see is gold. They are 23 grams each, 1"×1" square and about 1/8" thick. They each were on a copper heat sink. Any help is appreciated!

Low grade for board sort. Locally toss them in your copper barring material cbm or switches/copper cable ends if the have that class.

They aren't copper.....

Brass?

The heat sink there usually falls into copper aluminium radiator.

The switches I'm just basing on what the 3 yards i use class them as. Yes they're probably brass. One looks to be silver plated.
One yard i use has a class for power ends (#2 brass\silver or nickel plated #3 brass) and take all switches in that category as well 78c/lb on Monday

The other two don't sort ends out and take them as cbm/open transformers (switches cable ends and power supply boards and non-sealed transformers)
. 56c /lb on Monday.

Different yards take different things... differently. ;) ask them is my best advice but you're never wrong tossing in switches with cbm and/or motors or transformers if you only have a few.
