BU To You?

I know in the past Krause as well as others have differentiated coins from sealed sets (ie.; No handling issues due to bagging etc) from coins intended for eventual circulation (ie.; Especially in modern times bagged, even though they have no signs of actual 'use' or circulation). I think modern grading standards have evolved to some extent (for the better I'm not sure!) and that modern production and handling processes have definitely changed. It's just my opinion, but I think today there is not generally a distinction as you mentioned in your initial post. In 2007 I see lots of coins presented as BU that show bag marks, often more than I think are warranted by some of the high grades I see. I'm not encouraging anyone to use TPG's that do not believe there is any benefit in using them. But, I think that a judiciously graded coin given a numerical grade from MS60 up allows a way to distinguish between the true gem or choice coins from sets that are virtually perfect vs high grade UNC coins that may show noticeable bag marks and/or surface imperfections from modern mint and handling process without showing signs of true 'wear from circulation'. It'll be interesting to see what others add in this thread!
