1874 S Trade Dollar, Authentic? Or Fake?

Here's the punch line.

The coin I posted is a Serbian counterfeit 1874-S. It is within Weight Tolerance, but way off on specific gravity, won't pass an eddy current slide test, and is about 600 - 700 Hz off on a ping test.

Raw Trade dollars are dangerous. Even slabbed ones aren't certain. Both 1875-S and 1874-S counterfeits have been certified by major TPGs. At least with TPG certification, there is a guarantee, and I have never worried about a reputable TPG honoring the guarantee. The Chinese have a century of experience counterfeiting Trades, and the Russians and Serbs are darned skillful, too. The one thing none of them seem to get right is the reeding. On a suspect coin, always examine the reeding and count the reeds. If the reeding or number of reeds are wrong for the type, date, and mint, no further examination is needed.

A number of years ago, I was bitten by a counterfeit 1874-S, That experience spurred my interest in the modern counterfeiting processes. I am very wary of any raw Trade dollar since that experience.

Fortcollins, I saw that the coin you posted was a counterfeit and I did an overlay with the coin I first listed. I also did the overlay with the PCGS coin that I posted and it did align with It, it did not align with yours. Where can I find more information like reed counts for Trade dollars? Is there any place to identify die marriages as well?
What is amazing is that I have not seen any definitive comments on whether it is fake or if it is real. It looks like a mix of opinions from some very respectful members.
