<p>[QUOTE=&quot;bhp3rd, post: 835987, member: 16510&quot;]I spoke with Ken Potter regarding this yesterday.</p><p>&nbsp;</p><p>He said while on a mint tour he learned that mint set coins are struck with some higher pressure limiting the die life to approxamatley 125,000 strikes.</p><p>He said he had notes to this effect but could not locate them at that moment.&nbsp; The mint personal further stated that as always the mint tries to balance die pressure (in normal striking) to extend die life and produce the most coins of course.&nbsp; Those dies used to strike the 125,000 mint set coins would then be put back in service to strike normal coins.</p><p>&nbsp;</p><p>The higher pressures would or could account for a difference in how these coins look to me as I have said.</p><p>&nbsp;</p><p><u>What we still do not know at this time is:</u></p><p>&nbsp;</p><p><u>When did they do this, what years, all years, certain years, some years?</u></p><p><u>Was there any enhancements ever to planchets?&nbsp; Were the dies in anyway polished or treated different?</u></p><p>&nbsp;</p><p>I still strongly maintain that there is a difference, that the differents can be seen from 1959 to 2004.&nbsp; That I can see this difference and can show this diffence (in most cases) to others.</p><p>Also <b>that they never went to a bins full of buisness strike coins and simply pulled coins from there to fill mint sets.</b>&nbsp; From all mint sets I have ever seen and opened, this was never the truth, never!</p><p>&nbsp;</p><p>I refrain from saying the differents is only in strong strike.&nbsp; If that were all it is then early die state coins would be hard to tell from mint set coins.</p><p>I will try to explaine it again,</p><p>&nbsp;</p><p><i>There is a sheen, glitter, glit, shine, brillance, reflection, effect on mint sets coins that is not on buisness strike coins.&nbsp; Once you learn it it is simple to tell them apart.</i></p><p>&nbsp;</p><p>These higher pressures could indeed account for the appearence of this finish I am discribing.</p><p>This would also be within the mints (and others) descriptions of how mint sets are made because in effect nothing they have said is any different than what I have said here.</p><p>Mint set coins are struck from normal dies used to strike coins made for commerce, the planchets are the same.&nbsp; They are only leaving out increases in die pressure which they may have, or may have not thought important to disclose.</p><p>&nbsp;</p><p>I will follow up as I get more info. on this and let you know.</p><p>I&#039;d like to talk with Margoils, Q.D Bowers, Wexler, Crawford and some others if possible.[/QUOTE]</p><p><br /></p>
