I'm so sorry. It was just too tempting. I couldn't resist...
Love it !
Agree but I'd still call four of them 'tails'.
The three coins from Leontini seem to have the very same patina...
Here is mine, same obv die Rizzo Tav. XXIII, 2
@Barry Murphy you seem to have quite an enjoyable job at NGC ancients !!!
Why do I put a link to different Leontini coins: but it seems that I was right in my doubts and suspicions. Apparently there was for many centuries a whole business of making counterfeit coins for prototypes for which there were real coins from graves to be delivered to a carrier across the river of the dead ...
this coin miracle is worth 55,000 Swiss francs. I wonder if this coin did a metallographic examination to determine its age? I'm sure they didn't. That being said, I have to believe the unscientific conclusion of these auction houses where they are sold. And I do not know whether they are genuine or not. And without a scientific analysis of the metal and the origin of the metal of these coins, they are for me a beautiful forgery made, perhaps, 300 or 400 years ago.
Why so sure? I believe NGC sometimes runs the analysis to make the authenticity determination.
NGC (modern) will do metallic analysis and put the results on the slab for $75. See https://www.ngccoin.com/news/article/1591/ for an example of what that looks like. I have never seen a slabbed coin from NGC ancients with printed results. (If anyone has seen one, let me know.)
I went to NYC's "diamond district" last month but I was unable to locate anyone willing to XRF ancient coins in exchange for a cash payment. I did have a guy analyze a few for free (!!!). Dirty Old Coins used to have mail-order service to XRF for $25 or $75 and Ras told me there was very little demand.
what is written there is a primitive spectral analysis for the chemical composition of various metals in the coin, and I am talking about isotopic analysis, without damaging the coin itself, to determine its age and the mine from which this metal was mined, now such research is done in archeology. I do not want to trust experts, but to know scientific data ... numismatics is an exact science
