Question About Shipping From Canada To US

Since I collect Canadian and I live here in the U.S., I have made many fairly valuable purchases from Canada, and it usually takes around a full week and if it's sent registered or expresspost, the USPS doesn't leave it in the mailbox, you have to sign for it or pick it up from the post office... I wouldn't get worked up about the seller not marking it as shipped, there numerous reasons why he may not have marked it as shipped and most of them would have no effect as to you getting your coin...

USPS tracking is accepted by the postal systems of some countries of which Canada is one of them. A coin mailed by first class package from the U.S to Canada will tracked all the way until it's delivered and can be done so for less than $10. So, I am guessing Canada post would have a similar service that has tracking accepted by USPS. Anyways, it seems awfully risky sending a package worth hundreds of dollars without tracking.
