I have this large copper coin 15 grams 41mm, the nearest I can get to it is Turkey 5 Kurush KM#599 but that one is silver according to Krause. Mine is copper and has considerable wear it dates AH1223 AD1808
5 Kurush, KM#591. AH1223/22 1828 .2200 Silver(Billon), these will often look like copper after very little circulation
Thanks DCH, it was on the other page Duh!! Its the most copper looking silver coin I`ve ever had, LOL
