"Gold coins are set to a much stricter tolerance, especially as the weight increases" this contradicts itself...it shows the lower weight and lower value coins having a lower tolerance (as expected)...a double eagle has a .04 while the lighter coins, 1/2, 3$, 1/4 a full has .02 - if the statement were true, then the double eagle should fall to .01 (or so) not go up to .04
