'Rare' is a relative thing. People have a list of emperors or significant Romans and some think they need a coin of each one. Hanniballianus in...
If you want to see some rare ones, look up a copy of the Classical Numismatic Group auctions 12 and 13 (especially 13) when they sold the Kerry K....
Yes, but if you seal it in anything when there is a speck of remaining disease and even a little moisture, it will start again. Perhaps the best...
Also lets remember that there is a difference between worn coins and ones that have suffered damage since they stopped circulating as money and...
This thread has gone way past 'worn' into 'middle grade'. These last are way too nice. Many Roman sestertii were struck a bit weakly and on the...
Below are two ancient coins (both orichalcum dupondii of Nero). The first shows what I call toning. The brass is darker yellow but the bright...
Oops! I lied. I checked a coin that was treated about ten years ago and discovered the disease is back. The coin as it existed this morning is...

Terminologies can be a problem. 'Bronze Disease' is a form of green corrosion that is soft and powdery but, most significantly, produces...

Can someone provide a link that shows this coin type without the countermarks? 25mm 9.81g Failing that, do I have the right sides up?
A trade brought my way a few coins completely unfamiliar to me. This halfcrown of Charles I has several problems including clipping and there...

The OP specifically mentioned problems with Nazi coins and I suspect that the coins in question are those zinc things that tend to look beyond...
I agree that things look bad for this coin but can not help thinking that Missouri Territory 1856-61 was so remote that rules for the East would...
I just took on a job of photographing a bunch of coins for a small dealer and won't have time for much else for a few days. Included in the bunch...
