My friend asked me to identify some cob coins. I've spent nearly 30 hours researching them and I'd like some feedback please. I am no expert and need some assistance.
I think it is a 2 reales near 1730 from Mexico. I went to Silvertowne and had it put on the xray gun to determine metal content. 96%Ag 2.5%Cu 1.1%Au Mass 6.6g
This is coin 1
