Jammu Rupee: 1784 AD

[Rangnath]

From my limited resources, I gather that the coin was minted in the name of Ragit Dev posthumously in the year 1784.  His reign was between 1742 and 1780.  It weighs 11 grams.
Parasols (umbrellas?) have long been in use in coinage. Which coin can claim to be the first to employ it as a symbol?  I saw a prutah (online) of Herod Agrippa I that used one.
I understand that the parasol has long (from Classical Athenia? Where else?) been a symbol of nobility,  protection, the vault of heaven, power, rank, prestige and wealth from China and India to Ancient Greece. 
As for religious iconography, I know of the parasol's long standing use as a symbol for Lord Buddha. It is one of the eight symbols of good fortune in Tibet and Bhutan.  But in India, both Hindu and Moslem rulers used the parasol as mint marks.
This leads up to my question: why did the Raja of Jammu employ one on his coin? I can create reasons, but I have not access to information that will give support to my surmises.

The parasol is a symbol of power. As it blocks the sun, it makes the holder more powerful than the sun. This is wonderfully illustrated in the parable of the Japanese stonecutter. Note how the golden payong (umbrella or parasol) cannot protect the face of the king.
