1971-D Washington Quarter RDV Question

I am researching the RDVs for Washington Quarters...I'd like to try and assemble as complete of a die variety set as possible (without errors). I'm initially trying to create a checklist and simply learn about the set.

It seems fairly straight-forward except for 1971-D. I am finding different resources that say different things. It seems that the uncommon RDV-008 is consistent among the sources. But, the other variety varies based on source. Both Variety Vista and this really awesome resource I found from the Heartland Coin Club (http://heartlandcoinclub.com/links.html) indicate there were 2 reverse dies for 1971-D. But, Heartland's resource states the other (more common) variety is RDV-006 while Variety Vista says its RDV-007. Of course, neither show obverse photos to confirm it either way.

Does anyone here know...or does anyone here know someone who might know?

To me...RDV-006 makes more sense. RDV-007 was used from 1969-70 according to both sources (Variety Vista lists it also used on both the 1971-(P)/D issues). Both sources also state that RDV-006 was used from 1967-72 (Variety Vista shows it skipping both 1971-(P)/D coins).

Just based on chronological order...RDV-006 would make more sense to me. It makes more sense that RDV-007 was short lived and then stopped after 1970...than it does that they suddenly stopped RDV-006 for one random year in the middle of its "run" and then brought it back. But, I don't know.

Anybody actually know?

RDV-008 is the proof reverse, on a business strike coin .

 

Ive never seen rdv-007 on a 71 p or d. Im pretty sure only 6 and 8 occur on 71d and just 6 on 71.

 

OK...thank you. That's what I figured.

Also, I found a reference to the Type B-1...like a subtype of the RDV-002 for the 1963 quarter, but can't find any additional information to it. I almost wonder if there was a die clash that was polished our something which affected the die. I've only seen this referenced in one place. Any ideas?

Also, the Heartland reference lists "unconfirmed" RDV-003 for 1965 SMS, 1966, 1966 SMS, and 1967 SMS as well as "unconfirmed" RDV-006 for 1967 SMS. Has anyone heard of these being found?

 

@Rick Stachowski, are you familiar with a Type B-1 (RDV-002b) for 1963 or the "unconfirmed" die pairs listed above?
