Hello, May i have your feeling concerning this GALBA sesterce. Especially the patina that is surprisingly uniform on the whole surface of the coin: https://www.biddr.com/auctions/soleryllach/browse?a=2957&l=3329404 Thank you in advance!
I don't see anything wrong, but I'm not very good at spotting fake patina. From my perspective, it looks like a very nice coin.
Definitely a great looking coin, but I see why you might think it to look a little "too great". Unfortunately, like Bing, I can't say one way or the other with any confidence. I might be wrong, but at least in some cases, I would doubt this type of determination could be definitively made from a photo even by those with the appropriate expertise. That's the real pickle with buying raw ancients online. You have to trust the seller's expertise and/or integrity to some extent when making the purchase, yet, the last person that should be trusted is the one profiting from the transaction
I don't know anything about the expected style or really fabric of the type but I do see what to my eye looks like a thick, paint-like artificial patina which is rarely if ever a good sign. To me that alone is usually a sign to stay away from a coin
It does look a bit like it's been dipped in molasses, doesn't it? The brown goop would account for smoothing out the fields and making usually sharper details like the hair look a little muckier. Looks like a genuine coin though!
My opinion is real, but the fields have been smoothed or thumbed. I have a similar coin sestertius in my collection.
Bronzes can be very difficult as many of them have been fixed or improved in current times. Best to have a specialist examine it.
