The coin has been sent as a tracking letter that is with a follow up service. The last event recorded was the sorting center on the 02/06...It is not Blazed fault, it is without doubt the Post Office fault. However, i don't know if the post office lost it or steal it. I'll probably never know
Which country is it going to? I once shipped a coin to Spain and it took about 3 weeks to make it's way through their customs. When you raise a report that the post is missing, they should in theory, go to where it was lost and do a proper search for it. Unfortunately they're more likely to just pay a claim and say they looked for it. I try to disguise the coins in a square piece of cardboard (with bubble wrap padding) and try to stop them from rattling. Lots of tape on weak spots like corners helps too, but make sure it is flat and no tape can snag in the machinery.
