<p>[QUOTE=&quot;desertgem, post: 1796746, member: 15199&quot;]I propose each contestant develops and posts a thread consisting of 1-3 parts ( posts) demonstrating an important concept of the science of numismatics without the large % being self develops rather than taken from other on-line sources. Such threads could consist of positive effects or negative defects. Examples I will give here should not be used as actual threads as each should be personally proposed by the contestant. A positive thread could be on &quot;How to&nbsp; tell a proof coin&quot;.&nbsp; A negative piece could be on &quot;How to do a squeeze coin&quot;.&nbsp; Of course not to encourage such from being done, just to increase one&#039;s knowledge when making such determinations themselves. Others could be on grading aspects, magnifiers, microscopes, chemical analysis, etc. A person could use their own examples of coins, etc. or with proper attribution , other sources.[/QUOTE]</p><p><br /></p>
