Much appreciated. I figure someone with knowledge could rifle through them in 5 minutes and say something like "Retail value, $600, I'll give you $250", and we could both be happy. I have no desire to start putting individual bills on eBay or attending conventions etc., just want to get a fair market estimate, then arrive at a figure that leaves enough meat on the bone for someone who might resell them (or give a decent price to a hoarder/collector who just wants them all!). I started going through some bills on a collector website and indeed I have things starting from the very first series (though some in rough condition), but there's no way I could scan them all or type in all their serial numbers. I'm much too lazy for that, it might be different if instead of Canadian Tire Money I had Spanish gold doubloons salvaged from a treasure ship.
