Tyre Sheckel - Authentic Or Fake? What's The Date?

Wish we could see it without the bezel, IMO it's genuine just very worn and possibly clipped when it was placed into the bezel.

And about the holes ... would not they be bubbles of casting?

Prsferreira;

Spence is correct, you would need to take it out of the bezel. But that said, there are some things to say about worth. First, if this is a cast fake it has more value in the bezel as a religious item with a nice chain for someone in my opinion. As for what it is worth, the coin, if real, would be "fine" at best. So unless it was certified people will always question the coin and you will get like $75 in an open auction from people curious enough to buy it and that would be if the coin was removed from the bezel and people saw the edge and were still thinking it might be real perhaps. If there is a casting seam visible, the value won't be there. Coins like this, if real, could be made more valuable if NGC slabbed and graded it and potentially, (again if they agree it is probably real) the slabbed coin could sell $300-$400. But once they say it is not real to you the value is lost and you are out the $40 for the grading attempt. Finally as to what we can see, if the coin was struck at all with a hammer, and is not cast, a close inspection of the best letters available show the direction of the strike. Below I offer first your coin, the letters expended, and sadly I don't see evidence of a strike angle with one side of the letters deeper than the other. Below that I attach two photos from an NGC coin that sold and was just fine at best. Notice the coin looks very poor, but you right away know there is strike evidence visible. People will pay for a graded Tyre Shekel in any condition as it could be the one from the lot Judas handled. But if it was me I'd just keep it in the bezel and make a nice necklace of it.
