Is it legal to send a few euro to my son in europe? i have some left over from my visit there and wanted to mail it to him.
It is legal to send money in the mail (cash or coins) but there is always the risk of someone opening your mail and stealing the money. The postal system is not perfect.
no its just like sending someone money in the USA
It is legal to sell Euros to your son in Europe. It would be just like sending a normal mail to anyone in any country apart from the USA. The only disadvantage with sending money through mail is that it could be a bit insecure.
