About a month ago I received back 3 coins, graded and slabbed, from NGC and those three coins didn't spend a month in the system. This "story", in my humble opinion, was created when the OP required a signature for a package going to a Post Office Box. I think, if you would have seen what I have sent, Priority Mail Express, without ever having a lost or missing package, you might be shocked. And shame on me for NOT having one coin lost or stolen via USPS, since 1966. Maybe it's because I follow instructions?
