It would seem that the 1/1 example could potentially settle the argument, at least in the small confined of the world of sports collectibles.

Every player in a set has a 1/1 card made of them, all equally scarce in supply. However, the price for each will be determined by the players popularity (or perceived potential). Lacking any real demand otherwise, any given common 1/1 card with no interest or potential might sell or even sit unsold for under $10. Well below what you have to pay for almost any copy of the previously mentioned 73 Topps Schmidt rookie card with possibly millions of copies to choose from, but great demand.

I guess anything could be wiped out value wise if enough supply was to be introduced though. Unrealistic examples, but interesting to consider. Would the discovery of 1 billion previously unknown, mint Schmidt rookies make this card equal to a Von Joshua card from the same set eventually? How many newly discovered T206 Wagner cards would it take to make it just another "common" T206 HOF card and not the holy grail of cards?
