It's such a widely faked type. Has there ever been a "is this an authentic shekel of Tyre" post on CoinTalk in which the posted coin was deemed likely to be authentic? I doubt it. Hard to tell from those pictures but there may be a seam on the edges (which for this coin would mean fake).
Hopefully these people aren't paying more than a couple bucks for these. Also maybe folks are breaking up those fake sets of biblicals you get at shows etc. and just giving them out at church or something.
That said, I'm not finding a match in Forum's database, although that doesn't prove authenticity. From a practical standpoint, I'm not sure how you would authenticate this particular coin given the amount of wear. If there isn't a casting seam or other big red flag, you might have to send it to David Sear for authentication, or even to NGC (although NGC doesn't guarantee authenticity, Vagi and Murphy less likely than most to be fooled).
Here is an ancient counterfeit sold by forum - found on google- with an obvious seam it appears also. IDK maybe the OP has a chance of being one of "thirty"
The weight and a picture of the edge would help. I don't see a style problem, I would lean toward it being authentic just based on these pictures.
when i see a seam, it's like hearing a rattler, but i've an ancient strikeover that has what looks like a seam...just for devil's advocate sake
