I have a very poor example, I am certain that it is genuine and it is wafer thin compared to this chunky thing.

It's interesting, this same seller has an VRBS ROMA listed that looks very genuine, but has unusually smooth surfaces, similar to the OP coin, yet the reverse still shows flow lines near the outer edges. http://www.ebay.co.uk/itm/SUPERB-RO...em5d43e97272 |

I see that 3D printers that work with silver are available in Home Depot in the US and maplins and other places in the UK.

That's quite scary if 3d printers can be used to generate fakes, especially if you can scan authentic coins and replicate them...

I don't know whether it is possible, but the technology is improving all the time. I suspect it won't be long until..... eesh, I don't want to think about it.

Can 3D scanning reproduce the effects of the slow progression of silver crystallizationin in an ancient coin over a period of 2,000 years?
It is always possible for a very reasonable cost, to test the coin using X-ray florescence (XRF), looking for trace metals that would be found in the same proportions as for known genuine tetradrachms of the same period and mint.
I asked for some pictures of the edge of the coin. We now have them, and that is good.
For myself, an 'in hand' examination of the crack on the edge of the coin could be useful, using a 20X loupe. I would then compare with the cracks on other coins of the same mint and period.
Most specialist coin dealers of ancient coins worth their salt should be able to satisfy themselves, regarding the authenticity of the coin umder consideration.
