No, that was something I found in a group of coins I bought. This is something I found for sale online.
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.
Definitely not. Possibly a wedding token of some kind? I don't know. But I know it is not an Offa penny.
I collect Thai coinage and have many examples of Rising sun as well as conche shells. Your example is not said piece.
This is my AI answer ( not me ) This is specifically, a Merovingian silver denier or an closely related early Anglo-Saxon sceat (sceatta) dating from the late 7th to mid-8th century (circa AD 680–750). At 15 mm, it fits perfectly into the transition period where medieval European currency was shifting from small, thick gold trientes to wider, thinner silver deniers. Design Breakdown The coin is struck using a distinctly "barbaric" or Germanic abstract art style typical of the Migration Period and early medieval period, relying entirely on heavy pelleting (beading) rather than text or realistic portraits: Obverse (Left): A highly stylised central rosette or "flower" motif. It features a central pelleted circle containing an abstract six-petalled design or cross, surrounded by a symmetrical border of larger pelleted teardrops or petals forming a stylized starburst. Reverse (Right): A variation of a degenerate "standard" or geometric cross motif. The die-cutter used rows of dots to build up a central, swirling pelleted boss or rosette, framed by geometric, triangular pelleted borders. Classification and Attribution During this era, hundreds of local mints, moneyers, and regional rulers across modern-day France, the Low Countries, and Southern England produced unique, highly localized variants. Merovingian Denier (Most Likely): The heavy reliance on purely pelleted geometric layouts, rosettes, and the absence of any pseudo-Latin lettering strongly points toward a Merovingian regional civic or ecclesiastical issue from Gaul (such as Paris, Tours, or the Aquitaine region). Continental / Anglo-Saxon Sceat: If found in Britain or the Frisian coast, it could be classified as a continental sceat (e.g., related to the abstract geometric varieties of Series E, X, or rare secondary Series L variants). Moneyers frequently copied and adapted designs back and forth across the English Channel.
