<p>[QUOTE=&quot;Spark1951, post: 3224726, member: 90692&quot;]A compound microscope is a great tool for coins, just hard to get good pics without a built- in camera.&nbsp; I can see the effort you made and you got some pics that got the job done.&nbsp; You might look into an attachment for your scope or camera that will make it easier to take them.</p><p><br /></p><p>Also, study die creation and the minting process.&nbsp; These subjects will help you realize that the damage and wear you find on coins could not have happened at the mint.</p><p><br /></p><p>Pre-strike contact marks are common, they happen when the planchets are upset, annealed and fed to the dies.</p><p><br /></p><p>Many post-strike marks on coins are the result of the way they are handled and transported; contact with other coins in hoppers or bags.&nbsp; Later, they get put into rolls by machines that leave circular scoring on quite a few.&nbsp; Then they get a trip in armored cars and suffer from vibration that leaves scuff marks on the coins.&nbsp; There are many other ways that coins get damaged, including parking lots and fires.</p><p><br /></p><p>Hope this helps...btw, doubleddie.com has some of this info...Spark[/QUOTE]</p><p><br /></p>
