Not all Varieties are highly or even moderately sought after and because of this, a coin with a specific Variety may be valued less than a coin of the same Date and Mint of equal grade that is normal (i.e. without the Variety). Such is the case of the 1909-S over Horizontal S Lincoln Cent versus a normal 1909-S Lincoln Cent of the same grade. Now, when a new Variety is discovered and word gets out through all of the channels, it is often highly sought after as Collectors, Coin Dealers and Coin Experts alike often vie to obtain a specimen of the Variety or the Discovery Coin itself. Cases in point, are the 1992-P and 1992-D "Close AM" Lincoln Cents and the 1982-D "Small Date Copper" Lincoln Cent which have sold for big money and have nearly every Collector, Coin Dealer and Coin Expert out there scrambling to find one of these Varieties. Sure, your' 1918 Mercury Dime may have a lot of wear and damage on it making it have less eye appeal but if it is a new previously undiscovered Variety, then folks will scramble to find one of the specimens and at the same time, the value of your' Mercury Dime will go up because supply is not and probably cannot meet the demand per se.
