One of my collecting obsessions is the coinage of Probus from the mint of Lugdunum.
I have tracked down examples of most of the reverse types but there are still a couple that evade me.
I was very happy to recently added one of these missing reverse types to my collection. Oddly enough I didn't just add one example of the reverse type but managed to obtain two examples with different bust types within a month of each other.
The reverse legend of COMITI PROBI AVG is relatively common but primarily associated with the Minerva reverse type. The legend also occurs with Hercules standing left, holding olive-branch, club and lion skin. These tend to be a lot scarcer.
Dr. Pierre Bastien wrote a set of definitive volumes on the output of Lugdunum and this provides some insight into how scarce these are. Bastien lists examples with and without dots in the obverse legends as different entries. Since his death there have been two supplements to the series of books to include additional types and examples.
Here are my recent additions:-
Minted in Lugdunum (//IIII) Emission 7, Officina 4. Summer A.D. 281 (Bastien dating). Both coins are classified as RIC 71 Bust Type C.

Bastien 332 (1 example cited). Bastien 331 is the same type with dots in the obverse legend and he cites 4 examples. I have had information from Dr. S. Estiot, who has taken on the baton with documenting this coinage that this coin is now the second example known. Dr. Estiot has asked if she can add this coin to the forthcoming third supplement to the Bastien series of books.

Bastien 330 (2 examples cited) this example with an unlisted reverse legend break though this isn't unexpected. Dr. Estiot has confirmed that this is now the third known example with the other examples being in Oxford and Vienna.
I am now on the hunt for the same reverse type but with the more common cuirassed bust.
