<p>[QUOTE=&quot;GDJMSP, post: 3249791, member: 112&quot;]Best answer I can give to that is - it&#039;s a moving target. In other words, in actual practice when it comes to the TPGs there is no such standard because it&#039;s constantly changing. And the very definition of a standard is something that does not change.</p><p><br /></p><p>In general grading principles however anything that is on the coin that is not supposed to be there detracts from the grade. And hairlines, just like it is with almost everything else, are a matter of severity, and location. The more severe they are the more they detract, and when in certain locations they detract more than when in other locations.[/QUOTE]</p><p><br /></p>
