To summarize... this qiran belongs to a Kajar ruler.

Unfortunately the date is not clear. but one thing has to take in account for an attribution : the weight .of the coin.

With 4,90 g it is with no doubt a 26 nokhod standard coin(4,99-5,00g) and

hand struck.

If we refer to litterature : The qiran under the early Kajar rulers was of 36 nokhod std = 6,90g (Fath 'Ali, Ali Shah)

Husayn 'Ali Shah (1250) has reduced the weight from 36 nokhod to 30 (5,80g) and then 28 (5,40g).

Nasir al-din Shah also continues to reduce the weight :

- 1st std : 28 nokhod (5,40g) / 1264 - 1273)

- 2nd std : 26 nokhod (5,00g) / 1273 - 96)

- 3rd std : 24 nokhod (4,60 ) / since 1296 where qiran were

machine struckIn addition, it is noticed that no silver coins are known for Kashan mint for Fath 'Ali, 'Ali shah, Husayn Shah & Mhd Shah

(= 1212 to 1250)

So, if we take in account all these informations, this coin should be a qiran of the 2nd std of Nasir al-din Shah Kajar

the date is the problem... it ends by a "8" and it seems that 1278 or 1288 are not possible.
