What is the difference in the peripheral low grade and just low grade?

I believe a low peripheral will have more IC chips on it but still some of the waste such as capacitors and transformers vs low grade which is a brown board and contains a lot of the junk.

Are all green ones peripheral?

Much better chance if it is green. Best to post pictures just to make sure. I’m still learning l.

Here's a picture

There's been several threads that discuss the differences in grades. There's a more recent thread here:

That should be a helpful reference.

Regarding what you have, I'm 99% sure the brown boards will be low grade. The green board however may be anywhere from mid grade to high peripheral simply because the photo is terrible and I can't tell if some of the components are IC chips or something else. Make sure when your taking photos that the boards are in focus, which seems to be the main issue here. Lighting doesn't seem terrible but do make sure you have good even lighting and if your camera just doesn't take great photos try to frame the board so that it takes up as much of the photo as possible.
