Is the gold looking material on the board gold plating.

possible, but not likely.... usually the hue is skewed by the solder mask... Take a knife or something sharp and scrap the area over the traces. the solder mask should flake off and you should see the true color of the trace... if it is gold, it will look the same color as gold fingers. Most likely it will be copper though.

Let me know how many of those you end up with... I would go through Boardsort, but there is no way they would stay on the look out for one particular board and set it aside for me.

I usually tape a giant piece of paper to my questions and write a giant ? On it.
And wrap it in paper or paperboard. Then send my follow up email with the order I’d and tracking (as they request you do) and a note on it that says a big question mark board is included.

Especially with medical equipment it’s worth it. There’s no way to tell by a picture.

With medical equipment the traces are usually gold flashing over silver. But gold traces are not unheard of. mls has a good idea above, but be it gold trace or silver won’t change the class.
An ounce or so of clean solid silver contacts will though. Which is why I called out that board specifically for further review. Those wire brackets are literally life or death. Finding weird metals and alloys in med equipment happens often.

Wondering if someone could re-grade the boards that I posted back in 2017. Looks like some items now have more than one grade. Any Help would be appreciated,
