<p>[QUOTE=&quot;cpm9ball, post: 2630793, member: 24633&quot;]The easiest way to measure the degree of rotation is to mount the coin in a 2x2 mylar flip. Mount the obverse (heads) so that the unopened edge of the flip is at the top (12 o&#039;clock) and make the coin as level as possible in the opening using some horizontal reference such as LIBERTY or the date. Then, you can turn the flip side-to-side to view the reverse (tails). Think of the face of the flip as a clock. Each hourly increment is 30 degrees. Each minute is 6 degrees.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
