What Is Grade And Value Of Hadrian Denarius

this coin was found with a metal detector, I wish to buy it but its hard to determinate a price.

The portrait seems normal but the lettering does show some peculiar style.
Triangular punch marks seem to have been used to make the letters. The letter V in Augustus also looks smaller than the rest.
The S in COS looks like a backwards Z.
It is not unknown for detectorists to be conned by people "salting" the ground with a few fakes.
Without an up close and personal examination it is impossible to determine.
That said .....
If it is real (questionable) it might fetch $100 or more from a dealer

The coin looks off to me as well. It has a "soapy" appearance likely due to casting, and the lettering is unlike any I've seen on similar coins. I'd pass.

Many of us have been collecting ancients for decades. We've seen tens if not hundreds of thousands of coins.
But it is very difficult to judge authenticity by pictures alone, and I'm sure I have passed on a genuine coin which I mistakenly thought was fake.

The best way to avoid fakes is to purchase from a seller who handles ancients and guarantees authenticity.
Does the seller guarantee authenticity unconditionally? If not, walk away. You can find another coin from a seller who will.
