Vespasian From Same Batch

Mule? Modern fake? Here's one from the fake reports. Sadly, pic is tiny.

These have been knocking around for over 10 years.

Both coins may have well have come from the same die pair, fake or genuine.
That is how ancient coins are date arranged, that is, by die linking studies, based on the style of the die cutting.
In this case, style appears to be exactly the same.

IMO, the fake coin pictured appears to be fake, for three reasons:
1. - the coin looks to be far too evenly round, with no radial splits.
2. - the flan splits on OP's coin appear to be genuine.
----- to confirm, closely examine inside the splits with a 10x loupe, looking for tensile metal distress
XRF testing inside these splits may help to confirm if fake or not.
3. - color and texture of surfaces on OP's coin and fake appear to be quite different.

By appearance, the fake looks to be centrifugally pressure die cast, which is why casting roughness or evidence of bubbles cannot be seen, but reverse details appear to be slightly 'mushy', commonly found on first and second generation copies from original.
