When I was working in the middle east 20 years ago I bought these coins from a young soldier in Tyre in Lebanon. He claimed he found them there and needed money so I gave him a couple of USD and thought I would be a nice souvenier. Eventhough Tyre is an old town with many roman places ( I think them filmed some parts in the movie Ben Hur in Tyre) I think these are most likely just fake coins.
The thing is that I gave them to the museum for them tocheck if they were real and then they could have them since they had other similair ones there.
Today I got them back. They send me a postcard that they had done a inventory and found them in a bag with my name on it. And they wanted me to pick them up if I still wanted them. I asked them if they had checked them, but they had been forgotten and been misplaced and just found.
So after 20 years I got these back.
