I would say that it was worth 50 Euro cents, but now it has been ‘cancelled’ it will be worth its metal value based on 7.8g of 89% Copper, 5% Aluminium, 5% Zinc, 1% Tin.
Just because you can't see it ... doesn't mean it isn't there - Anon.
I have a German coin with a very similar cancellation. I see online that they can go for something like 20–30€ maybe? The only thing is that I'm not sure if such alterations (including mine) are really legitimate or just done by some guy in his workshop.
I read that they are recognizable by the type of signs they have on them, the rarity is given by the type of moenta and the country that destroyed them but I don't know more than this, I don't even know the value
