The 2017 classic designs are not being issued for circulation, but are available in the various uncirculated mint sets in standard circulation finish. They are also available in special wrapped rolls. As far as mintage goes, we'll probably have to wait and see how many of these products will be produced to know for sure.
As for the 2017 150th anniversary coin mintages go, I would guess that coins will be minted to suit demand. Special circulation coins (ie: glow in the dark, colourized etc) may have a limited mintage of x million.
