Potosi 1 Real Cob Coin (1618-1647)
Could you please verify the authenticity of this coin? It weighs 3.2 g and measures ~180 mm diameter (so I assume it is an underweight 1 real coin). Although it is fretted, I think I can read a P and T on the left of the shield (see image 3), making me judge it was struck in Potosi under Juand Ximenez de Tapia. Any thoughts on this? If it is real, what might its comparative condition be?
Hi Ludwig --
Very cool. It certainly looks genuine. I don't think it's underweight. Too bad about the hole.
I looked in the CoinArchivesPro database and found a few similar examples. Perhaps you can use this info to advantage.
