Message:: [QUOTE="Cherd, post: 3047469, member: 24754"]I've never been interested in coins that could possibly grade 70, so I basically have zero experience examining these types of coins. But in general, based on the strict definition of the word, "perfect" can only be realistically applied to things that have a finite upper limit (bowl a perfect game). When dealing with anything that occurs on a continuum (like condition), there is no such thing as "perfect". In this sense, perfect is like "infinity". We know what it means, try to get as close as we can, but can never realistically get there. So assuming or insinuating that MS-70 means perfect is faulty to begin with. You could take the best struck coin in history and find some kind of flaw. In the extreme case, you could put it under an electron microscope and find atom-scale imperfections in the surface. It may be silly to even consider this type of thing, but it does negate the possibility of correctly calling any coin "perfect". With this in mind, if the TPGs define 70 as perfect, then the highest possible grade that a coin could receive would be 69. As this is not the case, by default, their definition of 70 does not mean perfect. This means that they assign the grade of 70 based on the presence of some acceptable, minimal number of flaws. What that number or magnitude is? Who knows? This stuff is all subjective to some degree, so we can't expect much consistency.[/QUOTE]
