<p>[QUOTE=&quot;calcol, post: 24704199, member: 77639&quot;]Yup, 10 little piggies or fingers is almost certainly the origin of the most commonly used number base.&nbsp; But numbers other than powers of 10 are used for maximum scores in all sorts of human endeavors.&nbsp;&nbsp; Why do dice have 6 sides?&nbsp; Fair dice with 10 sides are easily made.&nbsp; Why is the maximum SAT score 1600 rather than 1000?&nbsp; So, no need to apologize for using a 70-point scale for coins.&nbsp; 70 provides enough range without resorting to a decimal point or plus additions even though such extensions are often used.&nbsp; Better objections have to do with the way the 70 points are distributed.&nbsp; Why are 60-70 used for mint state?&nbsp; Why don’t we rate obverse and reverse separately?&nbsp; They can be very different.&nbsp; Yeah, I know the answer … KISS.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
