Charlemagne, AR denier CAROLVS REX FR + MEDIOL Very rare; approx value around 3000 usd if genuine... unsure about that. Looks a bit off.
These cardboard holders would be relatively easy to make by yourself. I've bought quite a number of coins from this seller, and the dimensions of...
Well written, highlighting the attraction these coins have. The Abramson Auction was highly anticipated and postponed a few times. Prices went...
Cleaning coins can be rewarding, but sometimes, it can be frustrating. In general, I find bronze coins much harder to clean than silver ones: with...
Thanks all for the directions and IDs, appreciated. Indeed fun little coins!
This fun little coin grabbed my attention. It was part of a seller that regularly metal detects in Spain: [ATTACH] Head of Apollo (?) to right //...
Why so tense, @Clavdivs? Did Caesar take your silver as well?
Well, you said things like ‘read a book’ - but you’ve now deleted those posts. OP Posts his first ancient coin and writes a lengthy post. Whether...
Nice coin, and welcome to the dark side! Just ignore @Clavdivs. Caesar would have ignored him ;)
Thanks @Ocatarinetabellatchitchix. This would at least place the date of the ticket after Cohen, i.e. 1890s. Perhaps Belgian Francs? 350 French...
Thanks RC!
I've just added this nice Trajan denarius. It was bequeathed to the seller, who was so nice to include the collector ticket. Does anyone recognize...

This is incorrect. The deposits are typical of horn silver. Sodium thiosulphate will easily dissolve these deposits leaving the silver sulphate...
Looks fine to me. The black deposits are horn silver. I’ve written quite a lot on it; check my post history how to remove it.
This is exactly what I meant: you'll end up with a shiny coin. You may actually find a nice silver sulphate patina beneath the horn silver...
I personally never use this method, as it will also remove the silver sulphate from the silver coin, thus resulting in a shiny silver coin.
Thanks! There is no 'one size fits all' answer. It depends on the deposits and the coin. Regarding the concentration: some thick deposits require...
Thanks @AncientJoe. I think that's basically what auction houses are doing (that is, at least Leu). You are of course right, and I do stress this...
Hi, thanks. I've posted many guides on the restoration of silver ancient coins (which I regularly do). If you search my posting history, you'll...
