Take a glass/plastic bowl, layer it with aluminium foil, lay the coin in the bowl in such a way both sides are exposed, now pour boiling water and baking soda followed immediately, and let it cool for a while. Now take the coin and gently rub it with a tissue and wash off any residue.
I definitely wouldn't tamper much with the first one, I would be very concerned about that crack seen clearly on the reverse. Boiling/hot water especially would compromise it.
If you are into cleaning coins there are plenty of threads on this forum that discuss it in detail with good guides and references to good/decent sellers. Just search for 'uncleaned' and you should find everything you need. Otherwise, Like ValiantKnight said; there are loads of great looking coins out there for cheap if you know where to look. Good luck!
If so. Sodium thiosulfate removes horn silver very well. Dissolve some STS in a jar and soak overnight, and the dark spots will disappear.
Be aware that chemical treatments may erode the high points of the coins. I’ve found that lye will soften details in billon/silver coins.
STS generally doesn’t impact the fabric of the coins, but may lead to a rather dull gray appearance
The coins are corroded. Further cleaning will just worsen the situation with them.
They need to tone down over time (a very long time). The silver needs to darken, and it will, so the overall color is more even. The coins will look somewhat better, but the corroded surfaces will remain nonetheless.
Try storing them in paper envelopes and check on them periodically.
I didnt buy them. I was mainly checking future reference. Kinda trying to get the feel for buying conditions of what might be cleanable
The only way to know that well is by buying a couple hundred unclean and get a manual feel for it
