<p>[QUOTE=&quot;KBBPLL, post: 25838748, member: 104064&quot;]My best effort pretty much matches the seller images. </p><p>[ATTACH=full]1647458[/ATTACH]</p><p><br /></p><p>I&#039;ll further bore everyone with minutia, because this is what I enjoy about the hobby. In 1901, the obverse and reverse changed. During 1901 both types were used at all three mints. The first reverse type continued to appear sporadically in SF and NO through 1905, but the first obverse type is not found after 1901 (so far). It was previously not known that the second types were also used in 1900 New Orleans. </p><p><br /></p><p>Here&#039;s how to identify. 1892-1900 types on left, 1901-1915 on right. </p><p>[ATTACH=full]1647459[/ATTACH] </p><p><br /></p><p>I tracked the source of the 1900-O anomaly to this die shipment:</p><p>[ATTACH=full]1647460[/ATTACH] </p><p>I then identified those four reverse dies by mint mark position, all of which were the new reverse type. These dies were labeled II-A, -B, -C and -D.</p><p>[ATTACH=full]1647461[/ATTACH] </p><p><br /></p><p>It turned out that only two of the four obverse dies were Obverse II. These were identified by date position. The other two in that shipment, Obverse I dies, are impossible to distinguish from the other 1900 obverse dies shipped previously. These dies were labeled II-1 and II-2. (The image below is on the wrong order - II-2 is the top one)</p><p>[ATTACH=full]1647462[/ATTACH] </p><p><br /></p><p>All four combinations exist for 1900-O, and a census of 221 coin images shows the relative scarcity.</p><p>[ATTACH=full]1647464[/ATTACH] </p><p>My new coin is the II/II, around 6% of the 1900-O examples. </p><p><br /></p><p>I also identified five Obverse I dies that used the Reverse II anomaly by date position, labeled I-1 through I-5. I was surprised by how many anomaly combinations there were. An obverse die was paired with as many as three different Rev II dies, and a Rev II die was paired with as many as five obverse dies. </p><p>[ATTACH=full]1647465[/ATTACH] </p><p><br /></p><p>This all leads me to ID my new coin as die pair II-2 / II-C. </p><p>[ATTACH=full]1647466[/ATTACH] </p><p>Fun with coins![/QUOTE]</p><p><br /></p>
