Sell them on Craigslist locally would be your best bet. Another possibility which is more risky, is to find something you want on Craigslist in Canada and see if the Seller will take the coins in payment. If so, then I would take pictures to show the coins for payment, box them up but secure them well so they don't jingle or slide around, then ship them to the Seller with some kind of Delivery confirmation if possible. This would require a lot of trust on you part. Also, maybe you could purchase something from a TNnet member in Canada that is listed in the "Member Classifieds" and ship the coins to them for payment.
