Micro led controllers. Integrated.
Gold, yes. Throw them in a bin. When you have a few hundred they're worth refining.
Takes a few dozen+ to get bites on ebay.
They're worth about 40-50 per pound. Lol.

As far as board sort is concerned its a lowgrade board. If that ribbon contact plate below the leds are gold (can't tell) it will go midgrade.
