which dots are you referring to? bubbles are bubbles dots are dots. there are bubbles on the coin (small points showing casting) plus other telltale signs as in the face on the obverse. dots in the circumference aren't bubbles. it's most likely counterfeit from the pictures, but i'm no expert.
Since I just purchased my first of the type, I'm only vaguely familiar with the issue...and I just posted a thread of this denarius...From those I have seen at auction and those posted on the following link, I'm leaning towards a replica based on style and what may be casting bubbles. https://www.cointalk.com/threads/medusa-a-painting-and-jc.293817/#post- 2696631
Terminology: 'Bubbles' on casts are little recessed pits where air was caught between mold and metal. Raised bumps where the air was trapped between the original and the mold have been called 'pimples'. Neither is a good sign but I'm past feeling like it is safe for a person of my level to authenticate coins from photos. Would I buy the coin? No. I see a thousand coins I would not mind owning. I'm too old to buy coins that worry me whether they are guilty or wrongfully accused.
In my opinion it is likely a cast and I wouldn't buy it. The weight of 3.21g is also on the extreme low end which while not definitive proof on its own should make you very suspicious for a coin of this period.
I agree with both @red_spork and @dougsmit. I think it is a fake. Others might have a different opinion. But, why buy a coin you are not sure about when there are so many coins out there that do not provoke doubts?
The coin is a very attractive cast counterfeit. With better technique or equipment that would make an excellent addition to my counterfeit collection. As is... it is extremely crude and poorly made. Take the specific gravity. I see a silver plated fake with a copper core where the surface is flaking. As a general rule, any perfectly round depressions or raised pimples are a sign of bubbles trapped in either the mold or the "pour." Professional authenticators use the words "pimples" and "depressions" to describe the two types.
his mounth is to perfect, coin is to perfect anyway coin is to perfect/ letters are strange to me to it is fake in my eyes
This is not a legitimate reason to doubt this coin. There are high grade examples where these features are nearly perfect. The telltale sign here is not the perfectness of the coin but the evidence of the casting process.
