I need some help since Morgan Dollars are not my forte [opgelost]

My scales measure the weight at 26.85g (Numista page says it should be 26.73g)
My caliper measures the diameter at 37.95 (Numista page says it should be 38.1mm)
My first attempt at a density test (in cup of water) came out at 11.1 (should be silver)

So the measurements are not spot on but also not a long way off (could be tolerance in measuring equipment) but when I look at the coin it just doesn't look like a 134 year old silver piece so I assume it is a copy but for the benefit of myself and anyone else who doesn't know about these things and at the risk of coming across as some kind of noob, could someone please give us a bit of a master class and point out what are the areas to look for?

Thanks in advance for your help

It's not a particularly rare date, so if it is silver then I would doubt that it's a fake, it's a lot of trouble to go through for very little return.

I had a few that were off like this and seeing the steep rise in counterfeits, I sold them all without problems.

Did you try some silver tests?
magnet, pingtest, ice test....

My not-an-expert's 2 cents - looks like real one. No serious inconsistencies with the published pictures and the measurements (in my opinion) are withing the range. Little edge ding between 1 and 2 o'clock of the obverse, as well as rubs and nicks are consistent with typical bag marks, so unless it is an extremely high quality forgery (which I don't believe) - you've got yourself a very nice copy of 1883 Morgan. And judging by the number of the images of very well preserved 1883 Morgans on Google Image, it is not uncommon to find a copy in such condition.

Thanks for the feedback guys, I'll check out the links provided

Can you post images of the edges?

Haven't done silver tests yet but here is a pic of the edge:

In my experience, the areas where the forgers make errors on Morgan dollars, are the luster, dentils, date, and fine details of the devices. This coin looks looks good in all those areas; thus, I would check your scale against another coin, such as a silver eagle, to see if that's where the problem is.

Many thanks to you all for your comments and feedback. I don't know where the coin came from originally but it was left to me by a close friend of my wife who recently lost her battle with cancer. Based on what I have seen and read and from looking at the coin in hand, I am reasonably happy that it is the real McCoy and I will happily place it in my collection with a little reference to who it came from.

The coin looks original to me and, as others have mentioned above, it's not a rare date so it's not exactly worth faking. It could have been cleaned in the past, but I may be wrong.

​I agree for the cleaning, because the missing of a nice patina.
A nice test for silver coins is are the neodymium magnets.
If you have silver oins, it is a good investment to buy some (www.supermagnete.be):
