Hello again, friends! Do you happen to know where is this almost dime-sized piece from? Any tips are greatly appreciated!
Usually it's classified as AE, for bronze, and whatever the diameter of the coin, is. So if it's dime size, than say AE18. Nice bronze too.
I'm no expert at all, but it looks like it says on the right side of the reverse, reading down, "LAODIK[EON]. (Laodicea of Phrygia) Compare to a similar coin BMC27 at Wildwinds. https://www.wildwinds.com/coins/greece/phrygia/laodikeia/t.html
