I'm winding down to the last few things now.

Not sure what those contacts are on #7. I'm pretty sure #10 is silver.

Would the 1st board on #6 be considered backplane?

ACID TREATED, DO NOT SEND;
Back when I was young and stupid, about 10 years ago, before I became old and stupider, but more cautious, I mixed up a batch (CAUTION: DO NOT TRY THIS ANYWHERE) of home and garden chemicals after reading about stripping circuit boards. I dropped in a few whole boards. Instantly a dense cloud of fumes arose and expanded to a ball about the size of a small dumptruck, and just hung there in the air. Fortunately this was outside, and I had a heavy duty fan that would shake the leaves on a tree 50 ft away, so I turned it on, turned it on the cloud, and watched as the cloud of fumes drifted off a hundred yards into a wooded area still a coherent compact fog. When I dared to approach the container, much later, there were a few bits of plastic floating on the surface of the emerald green mixture, and the boards were squeaky clean. Not a speck of metal, gold, copper, iron, aluminum or solder or varnish remained on any of them. Admins: feel free to delete this post if you think it encourages dangerous behavior rather than warns of irresponsible experimenting.

I won’t expand on the method used as I can figure it out and it’s not safe; the green soup was definitely the metals.
The cloud... you probably wiped out some local wildlife with that (murderer). ;)

This one above however was an electrical acid removal. They set the board upright just submerging the edge in a small pan (probably Pyrex) with a copper plate and an electrical field.

As I’ve said elsewhere many times... unless you enjoy tedious work don’t self refine. I’ve tried every method from the Internet, from books in the 1800s; from Alchemy tomes of the Middle Ages.
You’re not going to get rich. You’re probably going to take some years off your life. And you could die if your lucky. Or worse if you’re not.

Here’s a real conversation.
YouTuber: now I have hundreds of dollars in pure gold
Me: no—you don’t. You have half an ounce of of apx 4/24 gold-copper blend. $13
YouTuber: but every click on my video makes me money. I’m rich
Me: good for you: but you’re still an arse!
