Request for a mint [solved]

Please add Sakastan, Sagistan, modern day Sistan to the list of Mints. Nowadays, this region is common among three countries: Afghanistan, Iran and Pakistan. Thanks.

The reference for the mint:

https://en.wikipedia.org/wiki/Sakastan_(Sasanian_province)

Mints are usually located in a city, not a whole province. Was it a moving mint?

On base of the references I found, Sakastan refer to a region in South East of Iran. There is not a referring to an exclusive city. Probably it is an exceptional mint name that refer to a region instead of a city. 

The Oxford Dictionary of Late Antiquity: Under Shapur II, a Sasanian mint was established in Sakastan (mint-mark: SKSTN, S, SK). From the first reign of Kavad I (r. 488–496) onwards, this mint was located at the provincial capital Zrang (mint-mark: ZR, ZRN, ZRNG).

One of references I found is as below:
