Need some opinion about a denarius

[MrZun]

I got recently a Very dirty coin and the i decided to Clean It up, i think It looks beautifull, what you guys think? Should i Clean It some more or Is It gonna damage my coin?

All the pics including the First one is the same

And after Just 5 min of cleaning, an odd thing got revealed, somo sort of damage that the coin got and the patina covered it above the coin close to the letters COS, is that normal or nothing to be afraid of or should i worry?

I would leave it alone. It's a perfectly respectable denarius as is.

The dark highlighting is sort of a desirable feature as the devices on the coin stand out as does the portrait. I actually had a very similar one (Domitian) to yours once. So if I were you I would not over clean it.

Looks in reasonable condition maybe work on the provenance

The dark grey area is the original surface of the coin, which has experienced some chemical reaction. The shiny parts are areas, were this original dark grey surface has been removed by cleaning. I would definitely leave the coin as it is.

More often than not, when you "clean" an ancient coin you will just reveal more flaws. I would recommend not revealing and more flaws.
