It&#039;s a fantastic presentation, with big graphical exhibits of number vs. date (using actual coins as markers on the graphs) and deriving expected time in circulation, as well as time to travel cross-country from Denver to the East Coast. Any summary would not do it justice, but I&#039;ll try to capture some of the highlights tomorrow. I&#039;ve gotten permission to take high-res photos of the displays, but I&#039;ll have to ask the presenter about posting them here.</p><p><br /></p><p>One bottom-line observation: they calculated a half-life in circulation for quarters of <b>56 years</b>, much longer than the Mint&#039;s 30-year figure; for cents, they found a half-life of only <b>13 years</b>.[/QUOTE]</p><p><br /></p>
