As an FYI, Ontario is coming out with their own geocoin soon which will be trackable on geocaching.com

Out of curiosity, would anyone be interested in Manitoba coins if they were say $10 each and trackable on geocaching.com? I think the design you have would look great as a high quality coin. We just went through this process for New York and I would be very happy to help get things rolling for Manitoba if you were interested in going that route instead of the econo-coins.
