Silver Coin with hole in it

[Guest Richard_I'm_a_Guest]

A friend recently found a silver coin, it looks extremely old and one face is either worn or never had an impression.

The weird thing is that the coin/token has a hole in the middle.

The pattern on the one side appears to be like a maze.

Does anyone know what it could be?

I'll try and post a picture if requested.

It was just found near a ploughed field.

A picture would be helpful.
