require assistance identifying an old Indian coin

The coin has a wave pattern on one side and a large J on the other. and is 14 x 15.5mm, 6.2mm thick and weighs 9.35gm.

The closest matches I can get is with Lunavada coins.

The orientation is probably wrong and I dont know which side is which.

Thanks John

My guess would be a Hyderabad dub, but I wasn't able to find a match in Zeno. Here's a different Hyderabad dub, just for reference.

Thanks Seeker55, the dub will a usefull reference for some other coins I have.

This coin has a lot more “vacant space” on it, the dub with more lettering is “noisier”

Maybe a crude copy, Ahmad shah is visible on 2nd, possibly a nagpur imitation
