Interesting, did you mention above that this sale is a joke? The OP sounds pretty serious albeit information could be missing that prospective customers are looking for.
I'm not sure what the symbols or engraving means, but it looks different for sure.
All the lettering is hebrew. I think the word in the 1st pic at 12 o'clock is Netoniel.
Both pics match the first row in my link, and the description below.
Based on this, I think there's a good chance the other two coins will be from the 2nd row
