What is the history behind the two Shah Alam II coins?

N#25862

N#25864

The only difference on the pages listed, aside from catalogue numbers, is the gold content, .996 vs. .917. Where can I find more information on this? They appear to look identical.

I don't find them identical. Look carefully at the dots on the obverse and the positions of the characters on the reverse.

But there's also another which is also similar:

N#25865 

(Based on a recent discussion these three types should be given different names to help distinguish the types.)

Coins with the same date and denomination should always have a specific coin name to make the distinction.

In this case, there are 4 types (and 1 subtype), all with the same denomination 1 Mohur and the frozen date AH1202. Maybe we can add to the coin name the date or period these types were actually struck (blue rectangle)?

Further distinctions: KM# 112 is the only one with vertical milling, KM# 114 is the only one with a crescent added.

Krause wouldn't be Krause if we didn't get conflicting information. In a previous edition (1984) only # 779a was .917 gold, in newer editions (2015) also KM# 113 (previous # 779.2) and KM# 114 (previous # 779.3) are .917 gold:

By the way, I don't know what the difference is between KM# 103.1 and KM# 103.2, the descriptions are identical, and only one has a picture.
