<p>[QUOTE=&quot;Conder101, post: 163681, member: 66&quot;]Die cracks are caused when too much stress in the die from striking the coins eventually causes the die to start developing cracks.&nbsp; The cracks normally develop from one stress point to another and the crack usually travels from on letter to another, or from a letter to a pointed feature on the central device. (Pointed features or corners on letters tend to be greater stress points than rounded or curved features.)&nbsp; Since these are cracks in the die, when the die strikes a coin metal is forced into those cracks resulting in RAISED lines on the coin.&nbsp; (Your comment about &quot; were they made by someone just trying to cut in half&quot; makes me think that tthe feature on your coin is probably cut INTO the coin.)&nbsp; On rare occasions a die will fail and develop a crack that runs all the way across the face of the die.&nbsp; his may show as a raised line running all the way across the face of the coin, or in some cases it will show as a &quot;Shelf&quot; effect where the die on one side of the crack is higher than on the other side of the crack.&nbsp; This is caused when one side of the lower die completely breacks off and shifts down but can&#039;t fall away because it is prevented from doing so by the collar that surrounds the lawer die.&nbsp; (If the upper die fails in this fashion the broken piece of the die normally falls out and a coins struck from that die shows the design in one area and a raised featureless blob in the area where the piece of the die is missing.&nbsp; This is called a &quot;cud&quot;.</p><p><br /></p><p>I would be happy to look at your pictures and give you an opinion.[/QUOTE]</p><p><br /></p>
