I have a question. I was watching one of those crazy YouTube musical videos where they show the top valued stamps - this one was for Canada. They showed a nicely centered mint copy for $130 000. This seemed a bit high so I looked it up. My 2015 Scott's has it at $60 000, which also seems a bit high. I have a really nicely centered used number 1 with a nice SOTN smaller bullseye post mark that I paid about $300ish for a few years ago. Did I get a great deal, are on-line prices foolish or is this stamp really going up? I am seeing large prices for used copies not as good as mine. I guess we really have to do major research before buying any rare, or semi rare, stamp on line. Buyer beware, big time!!!
