Does anyone know what this coin is? I bought it on eBay, where it was listed as a 1640 double tournois, but I can't find the exact same coin on Numista or anywhere (most of the times the portrait is looking right) and it's very perplexing. Perhaps the way I looked it up was wrong?
Also, do you think it's genuine?
diameter: (roughly) 35mm
