In reference to https://en.numista.com/catalogue/pieces460.html I am having trouble understanding this part of the years options
What does (fr) BE mean?
This is my coin (images below) which of the 2 is it.




Second question:
See NGC Link https://www.ngccoin.com/price-guide/world/canada-dollar-km-79-1871-1971-cuid-1034619-duid-1269857
Its the same KM# but the design is different. Any ideas?
In the Krause World Coins catalog this is what shows

Is there a mistake on NGC? or is something else going on?
Third question:
In Catalog there is no descriptive info on the differences between the 2 options on the years (other than mintage) how would I know which I have?
Thanks in advance,
Aaron
