Morning all, I've been rummaging through some bags of coins and came across these two but have no idea what they are or if they're even worth paying attention to. I've included images below. Any help, as always, is greatly appreciated. Thanks
I don’t recognize the one on the left - the one on the right is ancient, Chola : https://www.cointalk.com/threads/raja-raja-chola-1000-years-apart.375536/
It looks like the one on the left might have Bronze Disease. If it does, you should get it in some distilled water right away.
