<p>[QUOTE=&quot;dougsmit, post: 1867025, member: 19463&quot;]Great job!&nbsp; I agree with all points but found the advanced cataloging system quite easy to understand.&nbsp; It is based on his statement, &quot;It is anticipated that cataloguers and collectors will use as much or as little detail as suits the occassion.&quot; </p><p><br /></p><p>All coins have an Emmett number: E370 is an Alexandria bust right reverse of Trajan.&nbsp; If that coin happened to be from year 15 (L-IE), the number advances one step to E370(15).&nbsp; Currently there are no E370 coins from year 14 but if we find one it will be E370(14).&nbsp; He does not consider obverse legends as important as reverse types but lists them with capital letters so those who wish can take one more step and acknowledge that the coin has obverse legend C and make the number E370C(15).&nbsp; Do you want to draw attention to a special variety (listed or not) with a different style portrait?&nbsp; Just insert that code after the legend letter making our example E370Cb(15).&nbsp;&nbsp; He suggests placing an X after the E for numbers you made up to describe a coin not listed in his book but using his number system.&nbsp; Here is where I find some awkwardness in the system.&nbsp; If you find a coin with a new reverse that fits (alphabetically by reverse) after 370 and before 371, it becomes EX370A but if you want to go whole hog with the rest of the system and add the legend and bust codes, you have the A followed by the C from our example above.&nbsp; I would have used a decimal and name the new coin EX370.5Ab(15) which would be appropriate for the exact coin as our original example but where the reverse looked left instead of right.&nbsp; From the number thus generated you could not tell how the coin was different just that it was alphabetically after 370 and before 371 (Canopus).&nbsp; That same EX370.5Ab(15) would be equally appropriate for a coin with the reverse of the god Anubis which is not known to exist but fits this space if one were to be found.&nbsp; Emmett also mentions that his cross references elsewhere in the book use this system and gives the example that E370(15) equals Milne 633 or, abbreviated, E370(15)=M633.</p><p><br /></p><p>Clear?&nbsp; If you don&#039;t like this, I challenge you to come up with a better system that allows expansion to cover all possibilities in a more clear manner.&nbsp; Most people do not really care and just want a number to put on their eBay listing so they sound smart.&nbsp; For them, E370 works just fine and dandy.&nbsp; Obsessive specialists will like E370Cb(15) better and be proud of the number of X coins in their collection.&nbsp; It is hard to please all of the people all of the time but Emmett tried and really did not do a bad job of it.[/QUOTE]</p><p><br /></p>
