<p>[QUOTE=&quot;Robert91791, post: 3175903, member: 95853&quot;]I also noticed that some state or ATB quarters are not consistent with their thickness. This can attribute to their durability, resistivity, selective and pitting corrosion. The decrease in iron contents on the State and ATB quarters reduces the resistance to deposit corrosion. The metal composition allowed design characteristics with fine patters and sharp edges but at the same time attributed to the die deterioration of these newer coins.[/QUOTE]</p><p><br /></p>
