Suspicious Morgan dollar at a brazilian online marketplace (fake?)

Hello, I saw someone advertising an 1878 CC Morgan dollar (pics below) at a brazilian ebay-like website for the price of 2000 reais (about 379 dollars!!). The seller was very smug about her prices, so I want to ask if these appear to be fake or not.

Hard to be sure from a picture, best to be very cautious.

Copies are very cheap, and are usually silver-plated copper, so pass the magnet test.

AliExpress is a very popular source.

Silver-plated copper passes the magnet test just like solid silver.

Silver, though not attracted to magnet, reacts slightly to passing of magnet alongside. But - so does the copper 😕

Yep.  Silver plated (or not) copper reacts the same as solid silver on a sliding magnet test.  The obvious test (if it passes both magnet tests) is weight (along with checking thickness), maybe even the first test that should be done.

How much does it weigh? 
It should weigh about 26.73g if it were a real coin.

Try to measure the size of it as accurately as possible.
It should have a diameter of 38.1 mm.
It should also be 2.40 mm thick.

I am not an expert on American coins, correct me if I'm wrong. 


 

If it's fake, It's of relatively good quality. The qualities that lead me to believe it's authentic are the accurate mint mark for an 1878 coin and the cleaning marks that seem like the reaction that would take over silver. 

The flatness of the breast feathers could be a red flag, but then again, they aren't always fully struck, depending on the stage of the die. 

The date, which is blurred in the first photo, would help to confirm authenticity, but even if it is indeed authentic it's worth under $200.

Here's a worn, certified coin to compare to: https://www.ebay.com/itm/255576837103
