...not necessarily...rarity is a dynamic measurement, its based on known examples, which can change...pop reports r based on whats been seen/submitted n is also dynamic n constantly changes, but gives the viewer a reference point by which to make determinations on availability...no one really ever knows how many of a given coin is still out there, numbers can change at any time...if after, lets say 100 years, only X number of coins have ever shown up then thats a very strong reference point, barring a mini hoard showing up, of that coins availability...i have often attempted to purchase the majority of several "rarities" , 3 of 5, 1 of 4, 6 of 7, to just see what impact/influence i could exercise on the market in those areas, its been quite satisfying on many diff levels, n in two of those the coins have never shown up in any of the tpgs pop reports to date, read into that whatever one chooses....
