Narrowing Down The Lead Codices Script

I'm not sure why I did not realize this before, but I've noticed another possible source for the Lead Codices script presented thusfar (including some of the odder features, such as the omega-shaped shin):

Bar Kochba coinage.

Take a look.

Bar Kochba Revolt. 132-135 CE. AR Sela – Tetradrachm.

Bar Kochba Revolt. 132-135 CE.

This is a second century script and provided that this is a match, this means that the interpretation of the inscription under the menorah as "Elek Ba Tom" (as claimed on the codices Facebook page) would not be correct.

I'd also be curious if any of the iconography could be found on other Bar Kochba coins.

UPDATE Apr 26: According to Philip Davies' editorial:
"The list of dramatis personae is not complete, either: Robert Feather, a metallurgist who has written on the Qumran Copper Scroll, and seems first to have broken the story, has been in contact with Mr Sa‘eeda and has himself a theory that in some places the Hebrew letters on the sheets appear to stand for Bar Kochba, leader of the second-century Judean revolt against the Romans, and for the Rabbi Shimon bar Yochai, who according to legend hid from the Romans in a cave for 13 years and also instituted the Kabbalah."
