If someone could help me grade these boards that be much appreciated. Thankyou

Board 14&18 the rectangular silver boxes on those, I can't imagine they're mercury but can you see any identifying markings? Or take a close up picture of them.

I do not believe their Mercury either I removed one and it kind of looks like a crystal oscillator but I took a close-up picture top and bottom if you figure out what it is let me know I've been looking and can't find anyting even through Google Lens.

Yikes! If mercury is a possibility never remove the component unless you're sure it isn't!

In this case you're correct it is a crystal oscillator, just Google SBL-1XH and you'll find it.

Okay, * indicates potentially going up a grade, just not confident enough to make that call myself.

1/5/9*/10/11/16/19 High peripheral

4/7*/12*/13*/17*/18/21 Low peripheral

2/3/6/14/15/20 Midgrade

8 Low Grade
