Unidentified Coin (Not An Expert, But It Seems Very Old)

some questions:
- where did you find it?
- what are the dimensions?
- what material do you think it is? Is it magnetic?
- could you post a bigger picture (first picture)

The writing gives me a late late mediëval feeling.
Skandinavian?
Sweden Denmark had several kings with the name Christian

Hello and welcome.

I strongly suspect that it "seems very old" because it was deliberately made to look that way, rather than actually being very old. It's certainly in the style of a mediaeval European coin, but I've never seen one that looks like that, and it appears to have a gun of some kind as the central design theme on the other side. I would guess that it is a "renaissance fair" coin, made by somebody (presumably a guy named "Christian") demonstrating how mediaeval coins used to be made but using a design entirely made-up by them. It probably isn't actually made of silver like a genuine mediaeval coin would be; it appears to be made of lead or pewter.

Something similar to what 'Sap' said.
There is a guy who makes custom jewelry and has a facebook page under 'Christian Rex', perhaps he made them for his 40th birthday party. Or someone made it for those medieval custom/fighting parties.
