Supply/Demand
Supply and demand. We all know supply on our pre-war cards is quite low. However, the supply variable is nowhere near the importance of the demand variable for card valuation. Its almost like if you get below a certain supply number, the demand is almost non-existent. There has to be enough supply to drive values up - doesn't seem right, but thats the way it works with certain "big" cards. Thinking back to college economics 101, not sure the straight line supply/demand curve works as taught here with cards.
