Window card Dollars and Quarters from the Royal Canadian Mint

(EDIT: I just realized that this should've been put this in the Coin Info and Questions section)

Hey everyone,

I've been on the site for a little while now, and found the site and forum to be a great source of info as I catalogue the collection that my Dad left to me, so I was hoping that someone might be able to help me out with this one since I haven't found anything related after searching around here (other than a few eBay listings):

I just stumbled upon a bunch of window card dollars and quarters from the RCM, but don't see anything specifically listed in the Numista catalogue. I was thinking of listing them in the the coin's BU category, and adding something like "RCM window card” to the notes, but how would you guys recommend cataloguing these?

Just taking the first image of the Dollars, year 2000 N#467 , these coin cards etc are going to be the Brilliant Uncirculated version of the coin. 
 

They are not Proofs, or Proof Like and there was no Circulation issued for that year, so they must be the BU version.

OK, that's pretty much what I was thinking too.

I’ve got mine catalogued as BUNC  the same as other carded coins
