<p>[QUOTE=&quot;medoraman, post: 1014636, member: 26302&quot;]I would just point out Doug that you yourself stated that the tolerances were the range but it was expected that the average be 2.50. If the average weight of a bag of circulated coins was 2.438, or 2.475, then it is expected that they averaged 2.50 when minted, so they have lost weight due to circulation. Law of large numbers would make it extremely unlikely that every single coin in a 500 count bag would be on the low end of the mints accepted variance. Assuming that the average should be 2.50 therefor proves this bag is showing circulation loss. You cannot take a large sample and then say its ok for the large sample to be outside of expected value. You are correct when it comes to a single coin that it may not be due to loss because the range was plus or minus, but on large samples, like 500, that argument fails since there should be just as many high weight examples from the mint in there as low weight coins.[/QUOTE]</p><p><br /></p>
