Augustus49 Your coin is in all likelihood a new sub-variety. That is not a rare occurrence for coinage of the First Republic.
However, from what I have learned and observed, Mike Dunigan intentionally did not list all overdates. In particular the instances involving a simple repunched digit - 3/3 2/2 1/1 etc. were omitted far more often than they were included. To do otherwise would result in a very much larger book, and many (or most) of the sub-varieties would not add value to most coins.
In the case of these older issues involving hubs, there are also numerous overdates caused by the use of the hubs for more than one year as you allude to. The question of hub overdate versus die overdates needs to be fully sorted out before any real feeling for rarity can be determined.
Very few collectors of early 8Rs attempt to assemble complete date sets with all varieties included. I believe that is often due to the eventual realization that in this period every die is actually unique.
The problem with finding every overdate ever produced is very similar to locating every die used in a given year. Both are seen as being impossible by most people who have been collecting this series for years. Since Durango products were sold overseas for bullion, it is extremely likely that the output of many different die pairs simply no longer exists, because that entire output was shipped out as bullion and were melted.
