If the mail got lost, there is insurance?
That was envelope that incide was rare coins.
Until how much money it is possible to claim?
Thanke you.

There is only insurance if it was paid for and sent 'Internationally signed for' or if it was really expensive item it would have to go 'International data post'....to send this way is REALLY REALLY expensive !
