There appears to be some confusion. Topcat asked for help on his coins, and I provided the information. I did not clean his coins (at least, I...
Hi Glenn, I’ll send it when I’m at home (currently on holidays)
Both extremely interesting hoards. I would really like clearer pictures of both, but especially the first hoard. Early medieval are very rare.
Not sure if you mean my guide (since I mentioned creating a guide on horn silver removal)? It’s sort of finished, and it is available upon request...
On holidays, so brief reply. Silver chlorides can be found in this granular form. In fact, I encounter them usually on coins of high silver...
Hi: sure, please post some clear pictures and weight.
Iron oxides and difficult to remove. Check my post history for several examples. If you live nearby, I would happily restore it for free. Send me...

I don’t see any red flags - the pits look like corrosion and not the effects of casting. Could you share some photos of the sides? A casting...
And finally, Caracalla's ear had a minor deposit: [ATTACH] The HCl reacted with the silver, creating a layer of AgCl (i.e. horn silver): [ATTACH]...
Just for fun, I did another, dropping only 2uL of HCl at the right side of the head, and another below the right wing: [ATTACH] And after....
Some of you probably know that I like to restore ancient silver coins. Over the past few years, I've treated hundreds, both my own coins, but for...
Not the best pictures: [ATTACH] The coin weighs 10.90 g and measures 25.8 mm.
Thanks all for the positive and erudite replies. I’ll try to photograph and measure the coin as quickly as possible.
Last week, a seller privately offered me a few middle bronzes, including this one: [ATTACH] [ATTACH] (apologies for the mediocre pictures; I will...
