Well, no, not really! What I'm trying to say is a grade, both obverse AND reverse, are definitive grades. However, when it comes to giving a coin a number, as TPGC's do, other factors come into play, such as digs, edge bruises, corrosion, etc. (which they mark a coin down for number-wise) and this is where it gets confusing, because you can look up this magic number on the given TPGC's website and come out with a grade, such as EF? So, this is the essence of the divide (quite separate from the idea of whether you like your coins raw or entombed, or whether they are protected or not), because traditionalists will say a coins circulation wear is what determines the grade, not that aunt Doris used it to knock for a gin at the bar, or little Tommy rolled it down a hill for fun when he was 6. These are all things that affect eye appeal, rather than grade, IMHO! TPGC's have somehow managed to confuse the issue of a coin's wear by including damage and tonal qualities, etc. Hope that makes sense?
