This is clearly not a coin, so what is it

OK, found this among the coins I got from my grandma. It has vaguely same look as one euro coin, but it is really light and I suspect it is made from aluminium. The "MOW" could refer to a thing where people can strike their own coins, so what would this be then?

From the pictures, I think it is probably from a little kids cash register. Most likely from Finland.

Hi VRJoh,

That should be a crude replica of a 1 Euro from Finland.

As for the "MOW" inscription I really can't tell.

Yeah, thanks. Cash register idea is probably the correct one.

Hi!

For me it's a caddie token
