Is This Denarius A Fouree Or Real?

Edge splits can tell lots about if a denarius is fake or not.
If the blank was struck cool or cold, splits are more likely.

When the edge of the blank fails in tension, as a result of spreading under the hammer, metal distress occurs.
The inside surfaces of the split are very rough, where the metal was forced apart.
With a cast coin, the splits are copied from the original, and are much smoother on the inside surfaces of the split, and the split is usually much shallower.

With cast fakes, the is quite often the telltale signs of an edge join, or a filed off casting sprue.

Have a look for tiny spots of peeled off plating. These more often occur around the edge.

Comes from close examination of the 'black' collection of fake ancient coins that I maintain.
Most of them were obtained from leading public auctions, in job lots.

Very good for self education. I must admit, I also have a couple of very good educational books on the subject as well.

I got 'stung' once. That's what started me down this line of self education.

Bit too much out of focus for me, to make a comment of any value. Bit hard to examine surface texture of the metal, inside the splits.
Probably better to look at it yourself with a loupe, and make up your own mind, for your own education.
