Thanks for uploading the pictures, they should be a real help if we can find a member who reads Arabic and can read both the coins and the notes on the holders.
To try to identify your second coin (bottom 2 images) I did a search in my catalogue for Silver coinage of Fath Ali Shah with a date of AH1242 in Shiraz and the only hit I got was:
KM# 710.17 KRAN 6.91 g., Silver Note: Type E.
Date Mintage F VF XF
AH1242 — 8.00 12.50 18.50
These are the notes given for Type E:
E. Obverse, new form of the royal protocol, Fath 'Ali Shah Qajar Khusro-ve Sahebqeran, “Fath Ali Shah Qajar, Caesar, Sahebqeran (i.e., possessor of an auspicious conjunction).” The rial was abandoned except at Mashhad and replaced by a qiran (kran) of 1000 dinars weighing 6.91 g (Unfortunately there is no image in my catalogue for this coin).
Now for your first coin (top 2 images) I think the coin may be upside down in the pictures. These are the notes from my catalogue regarding the ruler:
Muhammad Shah AH1250-1264 / 1834-1848AD
Silver Types
All purely inscriptional coins of Muhammad Shah share a common obverse legend, Mohammad Shahansha-e Anbiyja, “Muhammad, King of the Prophets,” a word-play on the name of the ruler. All have mint & date on reverse, as in previous reigns. The types differ only in their weight standards:
A. Based on a kran of 6.91 g.
B. Based on a kran of 6.33 g.
C. Based on a kran of 5.76 g.
D. Based on a kran of 5.37 g.
E. Obverse: Lion & sun within wreath. Reverse: The normal Muhammad Shah legend, together with mint & date, all within a square. Same standards as type D, with which it was contemporary.
Without a given date for this coin, identification is a little harder but by searching for Silver coinage of Muhammad Shah in Isfahan I was able to narrow it down to either a Kran or a Half Kran:
KM# 790.1 1/2 KRAN 2.88 g., Silver Note: Type C AH1254
KM# 796.1 1/2 KRAN 2.68 g., Silver Note: Type D AH1257-AH1263
KM# 787.2 KRAN 6.33 g., Silver Note: Type B AH1251, AH1264
KM# 791.1 KRAN 5.76 g., Silver Note: Type C AH1252-AH1254
KM# 797.2 KRAN 5.37 g., Silver Note: Type D AH1255-AH1263
Again, without being able to read the Arabic inscriptions on the coin or the holder the next step would be to remove the coin from the holder (carefully and using gloves) and put it on a 0.01g scale. That's about all I can contribute at this stage so I'll say good luck and goodnight
