Good morning! A friend asked me to figure out what this was - found it in a 2x2 labeled "India Gold Mohur." It's convex on the first side and concave on the second (hence placing a worn Canadian 5 cent under one edge to keep it level.) Weight: ~ .5g Diameter: just over 8mm on longest side, just over 7mm on the shortest side. Apologies for the fibers on the coin, just pulled it straight from the 2x2 to get a quick image. What do you think? Genuine? Gold? Denomination and era? Thank you!
Obverse is same as this, but reverse and other specs are all different. Might give you a starting point though. https://en.numista.com/catalogue/pieces74199.html
