This is a common example of an Alexius III trachy, it came out of a group lot from the 80's and I bet this is the first time it was photographed. It is beautiful but very flawed upon its initial strikes. Time adding the patina improved it. Post your flawed beauties, whatever time period they are from.
The very worn and darkened state of this sestertius of Tiberius serves to highlight the beauty of the emerging countermark that it hosts.
Here is my Austrian Netherlands AV Souverain d'or 1749 Antwerpen Mint (mm "Hand") Empress Maria Theresia 1740-80 Coin is FDC/ but obverse was struck off a cracked die....
My Alexius III had much less shifting/rocking of the dies between strikes so the legends are poorly struck up compared to the OP coin. However this same situation made the reverse detail better. It will not be easy to find one of these with full legends and central details on the same coin.
Fat Flan … and I have always enjoyed this coin… Roman Republic Anon AR Victoriatus 211-206 BCE Jupiter Dioscuri Sear 49 Craw 44-1
This is my favorite ancient coin. Strong strike, very little circulation wear. Gorgeous dark jade patina. Unfortunately, that obverse patina really got the short end of the stick. Without the obverse defect, this coin would be an absolute show-stopper.
The newest example in my collection is this Julia Paula denarius, arrived today, sitting in the envelope for 20 minutes without being opened (personal record, but work load is erratic) I suspect I got a decent price because of the surface defects, but I don't complain at all.
