Dollarman apparently there are a lot of coins in the Victoria North part of the sale that are relatively new acquisitions in the collection. I wonder if the gentleman who put the collection together realized it would not be an easy task to assemble a finest known date set. In the Canadian series there are just some pieces that are impossible to acquire even if you have all the time and money in the world.
As to the 1945 Half in MS65 sure looks like it! I am sure that are more than a few collectors and dealers out there who do not realize just how scarce the 1945 is in GEM ICCS MS65 condition. A well struck full blast white GEM 1945 would be a numismatic prize! Few were put away and there is only one very small roll hoard that has ever surfaced of this date. Most of those were MS63 and MS64 and were from the Royal Bank of Canada Main Branch in Vancouver. They were subsequently sold to a prominent Vancouver coin dealer in August of 1968 and put away for a long time! ICCS report of 2014 states that there only 11 coins in 65 and a mere further 120 pieces in MS64,making the 1945 one of the toughest dates in the George VI fifty cent series .
