Interesting! I didn't care about centering as a kid (when most of us were much smarter), so I still care not a whit about centering so long as a card isn't actually miscut (worse than 99/1). Centering seems to be more of a focus for American collectors overall than for Canadian collectors.
Nonetheless I'm delighted that so many of you other collectors have a keen interest in centering. It reduces the demand for well off center cards thus making off center cards available for me at cheaper prices!
