A rare upgrade for my Registry set

SPP

I have the top set with circulation strike Canadian nickel dollars (1968-1986), but that does not mean I ever give up the hunt. These coins are equivalent I suppose to the US Ike dollars. I go through approximately $8,000 to $15,000 worth of nickel dollars per year, purchasing them at face value as bulk lots from dealers looking to get rid of them. To some, it appears to be a maddening exercise, but I have managed to build a pretty impressive collection where a good number of the coins only cost me face value and certification costs with PCGS. While I do have the #1 set, it is the thrill of the hunt that I love with errors or grade rarities. From my 2020 and 2021 searches, I sent about 30 coins to PCGS and got back some really nice grades (most as duplicates), but I do love rolling the dice and hoping for upgrades to my registry set. I do remain optimistic that the nickel dollar sets will catch on in time, as they are the last of the big Canadian dollar coins (prior to the loon dollars) and the last of the voyageur series.

These two are upgrades to my current set (the latter is a particularly tough to find in gem grades):
