I did see that there are multiple versions of this coin but I'm not sure which version this is there is anyway I can tell from the coin let me know otherwise I'm not sure.
If it has an L near the bottom of the headdress it is definitely bronze, I can't make it out with the corrosion on the coin. The color is usually a good indicator, it looks like the coin has been cleaned and it's hard to tell. I would guess bronze from the photos. Any other suggestions from some of the more experienced coin collectors out there?
