1918 I sovereign genuine or fake ?

[Mycoins]

Hello,

I newly obtained this Bombay- sovereign. What struck me at first was the colour wich is slightly more yellowish than that of my other one ( 1916 London ). While the London one hs a weight of 7,98 g , the Bombay oneonly weighs 7,91 g at the most . Size and thicknes are the same wich only can meen that the Bombay one has a lower gold content.

Is it known if the Bombay mint perhaps used used slightly less gold or is this simply a fake ?

The egde graining of the Bombay- sov by the way looks identicly to the London one.

Welcome to the Forum Mycoins

Not my area at all but AFAIK all sovereigns must contain precisely  0.235420 Troy ounces of pure gold at the time of minting, pursuant to the Coin Act of 1816.

So a genuine 22ct gold sovereign should weigh 7.98g

Thank you,Paulus for the welcome and your reply. A fake then. The colour arose my suspiscion, but the emense underweight gives it away.

I'm no expert either though if it is fake it does look half reasonable. All the same, the flatness of the top of the King's head and kind of rough surface are warning signs I think.

For what it's worth, here is my 1918I sovereign. There is no blob after the 8, the streamer looks to be slightly different and the depression running along the dragon's neck looks clearer on mine. The shaft on the left side of the ground is thicker on yours too.
