OK, probably good news. Not Lambo money, but better than nothing.
Bear in mind that I am a blithering amateur on Morgan Silver Dollars. I have bought and sold maybe a dozen, and seen a couple of fakes, and this could still be fake, but I just don't know it.
Weighs good
Looks OK
Not a rare date (this is good, rare dates get faked more.)
You probably have a legit 1881 Philadelphia dollar. From the amount of hair lines visible, and the worn down breast feathers, we are maybe looking at a "VF-20", kind of a C level grade. I think it would take more $ to get it graded than the coin would sell for. My book said there were 9+ million minted of this year, and VF-20 might fetch $35. I suspect that is optimistic-- I've gotten similar prices on eBay for Morgans, but your net ends up more like $25 after fees and postage. Those marks look like some bored doofus scratching at the coin with a nail or chisel, and won't improve the grading.
You may still have a nice chunk of silver. A coin dealer in town says he's paying $22 for coins like this right now, if you just want to turn it into a pizza. Avoid pawn shops.
Or maybe you want to keep it. It's got a secret that sets it apart from most silver dollars-- the worn surface shows that it was out in the world, paying bills, buying rounds of drinks, maybe convincing that dancing girl to peel off her silk stockings. 2/3 of Morgan Silver Dollars spent their whole existence unwanted, sitting in bags for a man's lifetime at the Mint. They were a scam for the silver miners, who, depending on the price of silver, could get dollar coins minted in exchange for as little as 60 cents of silver.
This one may have been in the West or Deep South, where they were more popular. Uppity Yankees preferred bank notes.
If I were you I'd take it by a coin store that has devices that can "read" the composition of the coin. They love doing stuff like that, and you'll know for sure.
PS: I wouldn't clean it or otherwise try to make it look better. People pay less when that happens.
