I am uncertain of the attribution. This coin measures and weighs between the two possible denominations listed in Svoronos.
Denomination E (Svoronos 482) is 24 mm with weight ranges of the cited examples ranging from 10.80 to 13.85 gm. Denomination F (Svoronos 483) is 20 mm with weight ranges cited from 4.75 to 6.85 gm, although there is mention of a specimen weighing 9.96 gm.
