That would be Fivaz and Stanton
system with the first Edition of the CherryPickers Guide
to Die Varieties, which came out in 1990.
Before that, there were collectors of die varieties who
started numbering systems, such as Jean Cohen, and
her "Classification and Value of Errors on the Lincoln Cent",
first published in 1970, although she had started categorizing
them back in 1967, if not earlier. Her book included RPM's,
die cracks, die breaks, clogged letters and numbers, BIE's,
doubled dies, and more.
(I have a first edition, signed autographed copy #356, that
I bought in April of 1970)
In 1972, the "BIE Handbook" was published with many hundreds
examples of BIE die breaks with detailed drawings, not photos.
They were numbered, but BIE collecting fell out of favor a few
years later, probably because 98% of them were just way too common.
One of the earliest, comprehensive and illustrated numbering systems for
Die Varieties was the 1971 publication of "Guide to Morgan and
Peace Dollars" by George Mallis and Leroy Van Allen. They both
had started to collect, examine, and detail Silver Dollar varieties
back in 1958 for Mallis', and 1963 for Van Allen.
Their interest was advanced by the 1963 publication of a pamphlet
by Francis Kleas entitled "Die Varieties of Morgan Silver Dollars".
That's about all I can contribute this thread, although other comments
might pry loose some memories from those time frames.
i have to believe that at least some of those terms pre-date the usa.
many foreign numismatists going back hundreds, if not thousands of years.

Are you talking about designations like FS-101?

No I'm talking about the CONECA numbers that PCGS does not recognize.

CONECA changed from the 1-O-I listing to the DDO listing in the 1990's. I think James Wiles was the person who brought CONECA around to this listing style. Kevin Flynn uses it as well and has recently challenged CONECA (and myself as attributor for Flying Eagles and Indian Cents) that he has ownership of the DDO listing style and that CONECA (and myself) should stop using it. Who "invented" the DDO listing style? I would guess it was John Wexler, who is usually in the forefront of numismatic evolution in the variety field. Can anyone claim ownership of a listing system? Can it be copyrighted, making its use under the control of a person or organization?
Is he claiming rights to the abbreviation "DDO" itself, or to a numbering system that uses "DDO-1, DDO-2," etc.?
The abbreviations themselves are simply old journalistic abbreviations used for the second and subsequent appearances of the full term. I would be amazed if they could not be found in the Collectors Clearinghouse columns of the 1960's and 70's, and the contemporary columns of Alan Herbert.

Tom,
Obviously you cannot claim intellectual property on a general abbreviation to 'DDO', 'MPD', ......, besides that not discussing in this forum as Rick and I will be resolving this in a different forum.

Correctly, it should be stated that Kevin is in discussions with CONECA, not me.
