Can we get the diameter, weight, and pics of both the reverse and the edge? Something off in the strike, could be ex-jewellery, could be cast.

It has the appearance of a 14K (.575) gold casting
Roman gold had a high gold content that was maintained even in the worst of times
If not for the current plague your easiest route would be a local gold buyer to test it
If it tests below 90% it's definitely jewelry
Over 95% and you might have something worth investigating further

Looks like a jeweler's copy, in good gold.
Best test at this stage is XRF, looking for trace elements, not gold.
The Romans were not able to refine their gold much beyond about 95% pure.
The surface texture on all parts of the coin is the same, no variation. That makes it sus to my eye.
Does it have an independently provable provenance?
Compare fake with genuine on

I don't think it is 24K gold
How are you able to determine ?
Thirty years ago I had some fun in a jewelry class nearby
They had some modest casting equipment for the full time students who graduated from the school
While everyone else in the class was sawing small pieces of plate silver to make 'trinkets' I was eyeing the kilns and the acetylene torch etc
I made a few coin castings (mostly silver) to mount or solder onto rings which I also cast
Gold was relatively inexpensive back then ($275 oz)
I got bold enough to try my hand
Alloyed gold comes out of the investment with a surface oxidation that you need to polish away
That is what I am seeing on your pic
Someone did the cursory 'buff' but you can still see some oxidation in the detail (portrait & legend) from the silver & copper in the alloy

The truth is that the coin is not authentic, but it is somehow beautiful

I believe the reverse is Jupiter holding victory on a globe. I don't believe an Aureus was struck with that type of reverse.

There is a curious 'lump' on the reverse rim at 7 o'clock, which suggests to me that it may have been cast.

The reverse is Emperor seated holding victory on globe and parazonium and though the coin that started this topic is not genuine, real ones do exist-- RIC Vii Cyzicus 286...though it is an exceptionally rare type. |
