I believe that you are missing a couple of slots in the Roosevelt Dimes 1950-Date, Proof Issue (Incl. Varieties) Registry.

Missing would be the popular 1954 DDO (FS-10-1954-101) URS-6, moderate interest and the 1956 DDO (FS-10-1956-101) URS-7, moderate interest. Granted they are both Class VI double dies, but with moderate interest and attainable rarity, It is my opinion these two dimes should definitely be included in any complete Roosevelt Proof Variety Set. Both are well known varieties with pictures and descriptions in well know publications..There is also a not so popular 1950 DDR (FS-10-1950-801) with an L-2 interest rating

Next, you need to either distinguish between the FS-10-1960-102a (early die state) and the FS-10-1960-102b (late die state) or accept them both for the 1960 DDO 102 slot. Make note that earlier graded specimens were not labeled as early or late die states by PCGS and therefore could be misrepresented.

Also in my opinion, the 1970s DDR VP-001 slot should be omitted due to extremely low population and very little published information.

Lastly, It is my opinion that no one should receive a ranking in a (with varieties) category unless or until they have registered a certain percentage of the listed varieties for the series. More varieties, lower percent. Less varieties, higher percent.

This may keep someone with a high ranking regular set from buying one coin and overnight becoming ranked number one or two in the (with varieties) Registry of a series even though they have no interest in variety collecting at all.

Case in point. Roosevelt Dimes 1950-Date, Proof Issue (Incl. Varieties) Registry. You are either a variety collector or you are not. Doing what I described above is completely unfair and reprehensible to someone who is truly trying to put together a world class set of any series with varieties included.

Just my opinion.
