Pennyman, the list is mostly complete for circulation loon-style dollars. You are missing 2020 UN colored. And two 2021 Klondike dollars (colored and regular) that are coming in August.
2003 crowned was not issued for circulation to the best of my knowledge. Though there 2003 Crowned with circulation finish
that were issued as RCM
products. Same for 2000 and 2001 - they were not for general circulation, but once they are removed from their sets they look like normal business strike dollars.
As for varieties, I find it interesting that there were distinct dies for PL and NCLT strikes that differ in the device size and legend font on both obverse and reverse.
I know of 2 kinds for years 2006 to 2009 and for 2008 Lucky Loon - 1 circulation and 1 PL/GiftSets.
For 2010 there are 3 varieties for each Loon and Vancouver.
