Roll Of Uncirulated 1965 Canadian Nickels

imagine a full UNC roll of 65 large beads nickels

Open them and be prepared for them to all be the normal barnyard Variety. That said you might find a really nice Heavy Cameo in high grade. The large beads 1965 is very elusive and was rarely if ever encountered in normal course of Commerce. When encountered they are Choice to GEM mint state which can lead to the assumption that it was more than likely a back door job at the mint or some other nefarious scheme. Certainly fits for that era.

not true, also you may encounter clips, or blanks which would be worth money

To be realistic about expecting to find a rare Large beads , a good read on the discovery of this rarity is to go to Ken Potters Variety website . The coin was not even discovered until 1996 by a Vancouver Washington numismatist, named Jerry Kennison . His comment was that they were found in a roll of PROOFLIKE Nickels probably removed from PL sets ( there are other theories).
As of the 2016 ICCS report the numbers are as follows. For the excessively rare LB ATTACHED Jewel there is a single Piece graded as MS60 then an AU50 2 ExF40 1 VF30 1 Fine 12 for a total of 6 coins.
For the slightly less elusive later die state DETACHED Jewel the population reads MS65 2 MS 64 7 MS 63 16 MS62 7 MS60 4 for a grand total of 36 mint state pieces. There are a further 4 pieces AU 55 EXF40 and a VF 30 plus a Fine 12.
For certain there are examples in PCGS and NGC holders as well. Of the two I have handled and the the examples that I have examined at coin shows over the years they all have a somewhat Prooflike appearance to them. Indeed many mintstate business strikes of the common Variety also have a somewhat PL appearance to them as well.
It is possible considering the difference in definition of PL between American and Canadian Numismatists that the original person to discover the Variety was mistaken and the coins were business strikes.
Highly doubtful that one is going to magically appear roll hunting Old rolls or searching bank rolls. But then you might come across a 1969 Large Date Ten Cents at the same time.

I never thought I would find a 1973 LB quarter roll hunting either .....
