<p>[QUOTE=&quot;Oldhoopster, post: 4906546, member: 84179&quot;]One way to get a reasonable estimate is to measure the length of the coin from the opposite rim to the edge of the clip (Vernier calipers work well). Since coins are struck in a collar, the standard&nbsp; diameter is consistent, so you can look it up (or measure it yourself).&nbsp; Quarters are 24.26 mm in diameter</p><p><br /></p><p>[(24.26 - length of clipped area remaining)/26.26]x100 =&nbsp; Percentage Clipped.&nbsp; </p><p><br /></p><p>It isn&#039;t exact but since clips are usually reported in increments of 5%, you don&#039;t need to worry if it&#039;s a 9.21% or 11.63% clip. 10% is good enough[/QUOTE]</p><p><br /></p>
