<p>[QUOTE=&quot;desertgem, post: 685485, member: 15199&quot;]Mike, I haven&#039;t seen any either, because it would have to be a coin I have watched from bright white to a toned condition (NT) with a missing color step, and although I have the prior, I haven&#039;t seen the latter.</p><p><br /></p><p>However, I think Doug has a point, because moisture and tone initiators, such as sulfur gases, etc., vary from place to place in the world, if a coin doesn&#039;t stay in the same spot, the proportion of toning activity could vary tremendously. It doesn&#039;t mean that the color progression would skip, it just might mean that a band could be extremely thin and not noticeable visually without strong magnification. </p><p><br /></p><p>It is like tree growth rings. We know there has to be a ring for each growth year the tree was alive, but some bands due to lack of water or sunlight may be so thin they are only seen with a microscope, whereas others, in good years, can be measured with a ruler, they are so large.</p><p><br /></p><p>But Doug, It was in 1934 that the French entomologist Magnan argued that, according to the known laws of physics, the bumblebee couldn&#039;t fly. It did take many years before high speed photography and torturing of bees ( making them fly in helium and carrying larger weights than normal) that they were able to see the variations that the bees can make in their wing arrangement to carry the weight. Before, no one could see the variation in the wings. So today scientists can explain how bumblebees can fly and even carry backpacks <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
