Hey guys, need some help figuring these out. KM #'s where available are also appreciated. First coin is a "cash" size. Second coins is small, thick and heavy. Third coin is very small. Fourth coin is the size of a US cent.
The last one is either a variation (silver) on the Venetian ducat or a fake of a gold version. You're not gonna find that in Krause. I can't make out enough of the legends to identify it readily, but I suspect it is either Italian or Hungarian in nature. I'll check what books I have and see if I can find it.
According to Hartill, no cast coins with the legend Huang You Yuan Bao have been found. Those listed by Schjoth were fakes. The coin looks to me to be a very worn Jing You Yuan Bao (Hartill 16.89 or 90) cast 1034-38.
The third one is from Pudukottai in India. It is an "amman cash" and was struck in Birmingham between 1889-1906. Fairly common. The fourth is Venetian style as mentioned, but I'm braindead on it at the moment...
