Old Indian Coin Authenticity, Identification

I can't say I like the looks of it but size and weight might be somewhere to start. Better photo's with the coin turned the correct way up would also be helpful.

Archimedes was asked whether a crown was real once, and came up with a theory about water displacement and specific gravity (weighing something both in and out of water and comparing measurements) This is a good way to test the density of metals without having to harm them with an acid test. Hard to tell from a photo but I am not convinced that this coin is real gold.

Here are a couple of reasons I doubt it.

1. The colour (though maybe the photo is changing that a bit)
2. The way the light is reflecting on the surfaces somehow looks wrong, like a guilded piece might.
3. Gold is very soft and this is supposedly old. I would expect the rims to be softer edges rather than really sharp.

Of course I may be wrong, someone more knowledgeable than I might comment on the type (which I am unfamiliar with)

It's 7.8g,
Definitely real gold as it's been tested with an xray gun.
I don't think the lighting does it any favours but I'll post additional pics shortly.

I guess my main concern Is if it's a recreation?

I don't know the type, and like I say it is hard to judge from a photo what material something is made of... if Echenzo says it looks OK then that's good enough for me. Maybe the photo does it no favours... if it has been tested then my concerns are unfounded.

Is the discolouration actuallyy discoloured or does it just look like it where its taken a bash and is in shadow (looks like the legend and the edge are angled from a knock)

The obverse style looks a little 'iffy' to me, but I will freely admit that I may be wrong, because I am not an expert with these.

What were the details for trace metals when testing with XRF?

The Kushans could not refine gold as well as in current times, and so there should be some trace elements detected if genuine. It is quite common for fake gold coins to be made in good gold, but of modern 'pure' alloy, with only copper or silver in the alloy.

I still say the coin look fine, though polished and perhaps a bit tooled.

This polishing is probably what made me say "the surface looks odd like its guilded" I would expect a slightly rougher surface with an old coin.

Does the xrf machine know the difference between plated/clad and solid gold? I have only ever tested with acid (no good for this task because you must break the surface first) do you have to break the surface with the laser test? Judging from the weight it all seems likely to be OK but I just ask out of curiosity.

here's the xrf analyser for those that were interested.

Thanks for the input above!
