How much do foreign coins weigh

Unknown foreign coins

Hello dear forum,

I was at the flea market 2 weeks ago with my 5 year old son and my 3 year old daughter and we bought an old piggy bank with farmer's paintings for my daughter and a Matchbox car for my son for 10 euros. In order to get to the contents of the pig, we would have had to smash the beautifully painted pig. I've never seen anything like that before, a sparing wine without a "removal opening".

That's why I always sat with tweezers during the evenings for the election discussion and tried to tinker the coins out of the slot so that I wouldn't break the beautiful piggy bank. By the way, there are still a few bigger ones in there that I just can't get out

I gave the coins to my children to play pirates in the garden and just wanted to ask where they come from.

Thanks in advance
