I was just given 25 of these. I'm guessing if I scrap them they'll be low grade(could be wrong but I don't see much of value here). The only marking I see is northern enterprises inc, and pn LED 2000AS, and CEC10(I think that's what the last one says) they're around 20" by 6". If anyone knows if they're worth anything for resale I'd appreciate some help identifying them. Otherwise help confirming the grade would be great! I also got a box with a few thousand of these LEDs, any value there? Thanks

Here's a pic of one

i would be inclined to say mid to low grade

Thanks for the reply. My best guess is low grade. They have 8 fairly small of the small black chips with fingers on 2 sides(can't remember what they're called), lots of LEDs, and small tan cylinders(around 40 no clue what they're called) looks like all lead solder so the only precious metals would be in those black chips as far as I can tell

That's a panel board from an led sign.
The board will go midgrade. There's gold in it but very very little.

They /are/ worth money if they work completely but testing them is a pain.

I have no clue how to test them so if they're mid grade I'll have to see if it'll be worth shipping them or if I should sell them at 10 cents a pound here. Thanks for the details
