Interesting comments and examples. Within a grade such as MS63, there are going to coins that are high examples and examples that received the benefit of the doubt at that grade. Coins are not created equal. We often look at coins within a series a compare coin x with coin y and think- How can these be at the same grade? Collectors seem to look at plastic thinking that one service is better than the other. Even a comparison between the two coins may not be an "apples to apples" in that the coin in the one slab could easily be better than the other. So even though both coins make the same grade, it really is the look and quality of the coin and not the plastic that dictates the value. What is disappointing is that this concept seems to be lost on those that merely look at plastic and not the look of the coin which is far more significant. So the plastic discussion as tot he better service is really is nothing to get excited about- keep looking at the coin and understand why the coin is holdered at the current grade. Make a determination if if is truly a quality coin for the grade- if not, look for one that meets your expectations.
