<p>[QUOTE=&quot;expat, post: 24557862, member: 111067&quot;]DDD can occur in many guises simply because of what causes it. The sharp, incused edges of the design on a new die will produce sharp, clear devices on the struck coin. As the die usage progresses, these sharp edges become dulled, clearly seen on the struck coins, a while later they spread and die chips occur because of the constant pounding of the dies against metal discs only slightly softer than themselves. The outer devices start spreading toward the rims and both sides of the devise spreads, and evidence of a ridge ring becomes evident.[/QUOTE]</p><p><br /></p>
