I recently bought a Japanese Ryō coin and am interested in collecting more of them but I would love to know if someone can help me to learn how to identify them.
In later Japanese coins the emperor is always stated with a symbol, but from what I can see these Ryō coins all have the same characters for a given denomination. How do you identify which emperor it is? Or is it just a matter or looking at the details of the characters? Is there a place I can find more info?
Also any tips on avoiding fakes?
