Yes, I'm going to be very cautious. I've been reading a lot and lemon juice seems to be the way to go. It specifically binds to iron and can dissolve iron oxide. Although, not going to try it just yet.

I don't think that the coin in question needs any cleaning work done, however, if you are going to have a go at cleaning this silver then I would soak it first, distilled water, then attack the stained area with a cocktail stick that has a soaked end so its quite soft. There are many different ways to clean coins and there are many different opinions on how to clean them. Another way to rid silver of rust like dirt is to heat the coin up then drop it into cold water then scrub with a short bristled tooth brush. The trick being that the silver will expand/shrink at a different rate to the rust like stain. As I am a detectorist, I find Roman coins in all sorts of different states and have learnt over a period of years how to clean them to a high enough degree to be able to list and sell them on our old friend ebay. The coin you are cleaning is a very nice example of its type so whatever you decide to do to it, do it slowly. I await future pictures!!  |

There is hope - just from a 1 day soak in distilled water. Something is coming off. I'm getting excited   |

Patience
It took two thousand years to form
A few weeks or months is almost nothing to you
Be careful about rubbing it
That's why I recommended dabbing at it
Any loosened particles could leave micro scratches and make the area dull looking
Lemon juice was the method of many dealers I knew back in the good old days
But it is acidic so it is worth keeping a close eye on if you chose to try it
Most "baths" won't effect the silver surface
But rubbing it can alter it

OK, I did rub it, but I haven't come close to penetrating through the deposit. No lemon juice just yet. If I do, I will update the thread.

I hate to be the one pointing it out, but the large "R" stamped into both sides indicate to me that this is a replica. So it probably isn't made of solid silver, hence the severe corrosion that has developed.

The R does not look modern
But .......
Being suspicious by nature
It does have an odd style to it doesn't it ?
I am staying out of this
Silver gives me gas

First time I've seen distilled water work so fast. Looks like that just might do the trick.

Don't think it's a fouree, it may have been buried by some bronzes? The deposit appears to be sitting on top of the coin. Bob - thanks for finding the banker's mark.
The style of the coin is fine, I found an example sold at auction, ironically with it's own banker's mark.

Still soaking in distilled water, but I've been treating the area with dabs of lemon juice for 15mins every couple of days. Yesterday I grabbed my cleaning pen and lightly brushed just the deposit without touching the coin at all. Trust me, I'm being real careful. The good news is that it looks like the encrustation is sitting atop the coin. Look closely you will see a bit of the denarius poking through.   Edited by travelcoin

Hornsilver can vary from black to purple to reddish-brown to yellowish, hard or soft, crystalline or amorphous. A possibility?
