<p>[QUOTE=&quot;Conder101, post: 2879636, member: 66&quot;]Striking pressure can result in slight differences in the ring as can whether or not it is struck with or without a collar.&nbsp; For struck without a collar the diameter and thickness will also vary which can also affect the ring.&nbsp; Slight differences in alloy can have an effect as can tiny internal cracks and voids in the metal.&nbsp; Ring can be a clue, but it is not reliable for counterfeit detection. (Sometimes a internal flaw in the metal can result in the coin not ringing at all.&nbsp; This is known as a &quot;dumb planchet&quot;.)[/QUOTE]</p><p><br /></p>
