<p>[QUOTE=&quot;physics-fan3.14, post: 2352850, member: 19165&quot;]There are several theories as to why the New Orleans Morgans are weakly struck from certain years (this affected the later years more than the earlier ones). The theory which I like the best has to do with the way the planchets were annealed. The mint had the same equipment as the other mints, but they annealed their planchets differently. This affected the hardness of the coin, and made it more resistant to accepting the strike.</p><p><br /></p><p>Grading New Orleans coins is slightly challenging because they are graded on a curve. That is, you can really only compare the O mint coins with other O mints, of the same year. If a year is known for a weak strike, it won&#039;t get punished as much for it. You can never compare the strike of an O with a P - they just won&#039;t ever be the same. Old timers really don&#039;t like this market grading, but this is how the TPGs will grade them.[/QUOTE]</p><p><br /></p>
