I am a huge John Lennon fan and a collector of NCLT however I am going to wait until I see this in hand. The laser etching done on the medal that was part of the 2005 Netherlands set would be great for this... If it is just a screen print (like the 2019 standard proof set SD) then I am less interested.
It is interesting though that finally, we have a pop culture commemorative that ties directly to Canada with the Montreal Bed-In, unlike the Warner brothers/DC Comics coins of years past where I struggled to see the Canada connection. This is a good step forward in concept and recognition of Canadian tied events, breaking out of maple leaves, polar bears, arctic foxes and the two world wars. I also like the fact that the anniversary is a standard recognition period... 25,50,75,100 yrs... in this case 50. I am not sure I understand the Victoria Jubilee Stamp from 1897... celebrating the 122 year anniversary...
Even the St Lawrence Seaway 60th anniversary seems forced. I am also glad that it is not on an egg shaped or guitar shaped planchet. I also collect guitars but a guitar shaped coin makes as much sense as a coin shaped guitar.
Hopefully the execution matches the concept.
