I saw this beautiful coin of Justinian at a coin shop in ma-shops.com: It was so beautiful, however, I noticed something was "weird". What was "weird" I could not put words on. Later I read the discription, and I find out that the reason I though it was "weird" was because: It was TOOLED. Justinian's hair must be added. Otherwise I'm not sure 100% what more is added. Are there other examples of byzantine tooled coins? How do people tool coins? What instrument do they use?
