Funan Kingdom Thailand have similar coins. Rising sun silver coins In the subway now so I can't provide more information Probably not
Ai says This image shows a rare 1200-year-old silver penny from the reign of King Offa of Mercia. Item: Anglo-Saxon Silver Penny Date: Circa 757–796 AD Origin: Mercia, England Design: Features complex beaded patterns and a serpent variant. How true is anyones guess.
I tried AI image search a few times and got different answers each time. Looks like it's not Offa's either. https://en.numista.com/catalogue/in...v=&cu=&a=&dg=&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g= My best guess is it's either not a coin/token or like @Pickin and Grinin said, it's a privately made piece.
