Hi all,
I guess because I collect
severan period debased
denarii I don't often encounter horn silver and have little experience deciding if an encrustation is horn silver or just old dirt & minerals. From what I have read, copper-alloyed silver is generally much less susceptible to horn silver corrosion.
This coin has a few pin-point size encrustations that are lead-colored, which I know is the color of horn silver, but I don't usually see photos of it that look this small and isolated to little bits. I've only
had the coin a short while, so it's not like I would see the progression yet.
Just in case, and on the general idea that I will encounter horn silver eventually - after reading up on it I ordered some sodium thiosulphate powder online just in case - won't have it for a week or two though.
Most of it is around the L in IVLIA, but there are very tiny specs of it on both sides of the
flan in isolated areas.
Should I do a precautionary sodium thiosulphate bath with a DW soak just in case?
