Yep, LED's have Gold in them.
If you do them yourself, there is a method called 'Patnors method'. Basicly you put them all in a metal container and reduce the plastic to carbon over a fire.
Then pan the Gold wires out using a Gold pan.
Theres still Gold left in the dust and on the Copper leads. Thats a different method and the strongest acid we use on Scrapmetalforum is vinegar.
Its possible to sell them on ebay, probably the best idea.
I am saving the LED's up. But I am also saving up scanner bars from printer scanners, they have a row of LED's and about 250+ Gold wire connections.
I pulled apart a inkjet printer head and found a bunch of thick Gold wires connecting under the actual printer plate, the part with the rows of holes where the ink comes out. It had a Ali heatsink or mounting around it.
Inkjet printers are cheap, but the actul unit has a whole bunch of Gold wires in it, in all different places. LED's, scanner bars, contacts, cartridges, inkjet plate, optocouplers, IR LED positional counters for reading the holes in the plastic discs.
It just don't make sense to me, too much Gold.
