There are three edge variants. What is written on the edge?

Hello and welcome to Numista!

There is one value on the coin page for a VF coin.  I'm not saying your coin is or isn't real. It would help if you would give the diameter and weight of your coin and, as already been suggested, pictures of the edge.  In your pictures it doesn't look like silver but that may just be the lighting.
