Hello everyone! Sharing an interesting piece. Numista specifies the weight to be 13.1g, this piece is overweight at 13.7g
The Obverse with the coin in 2X2 cardboard flip

The Reverse with the coin in 2X2 cardboard flip

The Obverse for a clearing view

The Reverse for a clearer view

Below are pics of the diameter and thickness with a rather crude Vernier:


13.7g

Is this a dual type error coin? Is it Cud error with Die rotation error (I measure 15 degree) or a Counterfeit? What are your opinions?
Thank you
