<p>[QUOTE=&quot;cladking, post: 21879, member: 68&quot;]I don&#039;t really believe in MS-70 on several levels.&nbsp; First is that I don&#039;t believe that any coin can be truly perfect.&nbsp; Even if you could show a few coins that really deserved the grade, they could still be separated best to worst.</p><p><br /></p><p>No modern regular issue of any series has ever been graded MS-70. Indeed, other than a small handful of ultra-moderns, none has ever been graded MS-69 either.&nbsp; </p><p><br /></p><p>A good rule of thumb for most of the moderns is that 10% of mint set coins are choice, 2% are gem.&nbsp; Generally about every fourth gem is choice gem and evey tenth choice gem is superb gem or better.&nbsp; You have to play around with definitions a little to make this work for some coins because they are skewed up or down the scale a little.&nbsp; Also some gems will not necessarily show full detail like full steps or full torch etc.&nbsp; There is significant variation from these numbers in any case.&nbsp; Gems can be as scarce as about .25% or as common as about 7%.&nbsp; </p><p><br /></p><p>Gems can be found in rolls and in many cases this is actually a better place to look for mark free coins.&nbsp; Finding coins with good strikes in the rolls is extremely difficult.&nbsp; </p><p><br /></p><p>Monsters (MS-68) appear extremely irregularly and almost certainly don&#039;t exist for most regular issue moderns.&nbsp; Some dates that are common in gem will be very tough in choice gem and others which are tough even in lower grades aren&#039;t especially tough in the high grades.&nbsp; Any analysis has to be done on a series to series and date to date basis.[/QUOTE]</p><p><br /></p>
