How to read Sassanian coins “chapter 1”

Where we find the Ruler's name & crown
Where we find the mint mark?
In this chapter will highlight four keys :
1- King name
2- Date
3- City
4- Crown
Before learning any script we have to know how to identify the location on coin . and these keys are constant on Dinar , drachma and falas / fals  ( some times they vary , but 80% same )
As you see in the photo
