Note:  It is likely the types with low numbers are overrepresented. That is, they are rarer than they appear here. When a collector already has many coins of a design and is shown a number of examples to possibly buy and add to the collection, he might buy the whole batch, but is more likely to select types he recognizes as rare, which increases the representation of the rarer types. 

MA Coll = A private collection, counted April 20, 2010.
Wd Coll = A private collection, counted September 23, 2021.
*DNE = Does Not Exist (It is in RIC but does not exist)
* The coins from the "probable error variety" are all from the same die.
* The "PP" of the faulty legend might be the normal "PF" deformed from die wear or the strike. I do not consider this a type different from type 1. 

*The RIC rarities in column 2 are from RIC VI which was published in 1973. After the Iron Curtain came down in the 1990s, a flood of coins from the region of Siscia commenced and has not let up. The rarities of coins from that region have changed dramatically. These types, formerly "very rare" (R2) or "rare" (R, as listed in the table above) have mostly become only "rare" or "scarce" and some are now almost common, although there are still dozens of GENIO POPVLI ROMANI folles for every quarter follis.
