Attribution Nomenclature

Call me impatient but the fact is I hate waiting.  I find stuff all the time that has no attribution listed by any of the Big 3 or is something that would be attributed as a lesser die variety.  Rather than sit on my hands waiting for someone to attribute my finds, it would be easier for me to assign attribution nomenclature.  I've already started with that Effigy Mound clash die.  Prudence and uniformity demands I come up with more formal nomenclature parameters.

Start with a general description, move towards a precise description:

Denomination - Date and Mintmark - Variety Type - Listing

Axiom #1 tells us there are exceptions to every rule so there will need to be some flexibility in how this is done.  Denomination is all well and good but there is a 1909 cent with an Indian on the front, another with Abe Lincoln.  There's 5 different quarter designs for the State or ATB Quarters in any given year.  I will need more information to disambiguate some coins.

Denomination - Date and Mintmark - Disambiguation - Variety Type - Listing

That should work.  I mostly deal with US coins.  I suppose I'll need to add Country of Origin as needed.


Denomination

Half Cent	1/2C

100 Dollars	$100

Date and Mintmark
This is fairly straightforward.  There may need to add disambiguation for Large Date-Small Date and other design varieties.

Disambiguation 
This deals with finish, composition, design type when more than 1 major design is used for a given date and mintmark, and other necessary discriminating information.
LD  Large Date
SD  Small Date
PR  Proof
RP  Reverse Proof
FM  Frosted Matte Finish
SF  Satin Finish
EH  Enhanced Finish
CU  Copper
SV  Silver
ZN  Zinc

Wexler puts a W in front of his DDO to make WDDO.  I'll use...P.

Listing
The number I assign.  I'm thinking I'll try to match it up with CONECA as much as possible.
If that's not good enough, CONECA will simply have to change their ways.
Different dies of the same variety would have a decimal added.  For example, a 1988-D 1c RDV-006, Die 3 of 3 would be 1C-1988D-RDV-006.3.
