2016 50th Anniversary Mint and Proof Sets

[Cougar]

To the best of my knowledge, mint set coins are the same as circulating coins of the future except some of the coloured $1 and 50c coins.

Another exception is the 2015 50c that is circulating at the present. A COA instead of the anniversary 50c piece.

Could we add 2007, 2008 and 2009 20c mint set coins to this list? By memory they weren't issued for circulation either?
