It's a coin which was struck at the city of Tyr. It could be a coin of the autonomous coinage of this city or a seleucid coin struck during the domination of this dynasty on Tyr.
But with these photos, the coin seems to be a fake. If you can do photos without the plastic, I would able to tell you more, about authenticity, and about identification.
Outside of the obvious, monetary value, why choose such an odd coin? Easier to cheat somebody (no internet in the 1960"s or home computers for that matter)? Easy to strike? Alloy easy to obtain?
Just curious?

Replicas of ancient coins are sometimes sold in museum shops.
