Hello all I have a friend who was asking me about authenticity for the Agrippina I coin above. Although it looks good to me, I am looking for more opinions. What you think? Thanks in advance!
This may help, if you have time to carefully peruse through the shown examples. https://www.forgerynetwork.com/view...f2vYy3sF2SpMb5EMxrg==&srco=1&num=20&srchall=0
Nice patina, but the coin underneath does not look very sharp... et la tranche est assez suspecte... I don't like this : I would say : cast fake
The patina looks good, but I'm suspicious of it. The devices (particularly the portrait) and the lettering just look a bit "off" to me. But take my opinion with the proverbial grain of salt. I do not have the expertise to render a truly informed opinion on this. I'm just posting my intuitive impression of it.
Agree that the patina looks authentic, but forgers have gotten faking patina and distressing coins down to an art these days. I agree that the host coin design looks mushy, and I would avoid it. In my eyes, this is probably a fake. I just don't see the details in the eye and hair that should be there if it was a genuine coin, even if worn.
Accelerated Weathering Chamber. We used to test our outdoor products using this to simulate long term weathering of steel, metals, uv plastics, etc. This was to test materials intended to be used outdoors for years in simulated long term weathering. I imagine you could do a good job putting a “natural” patina on copper, brass, and bronze “coins” over a longer testing time frame.
