I believe that the Freeman 2 Gold proof was sold to a Japanese collector. I believe the auction hammer was £6000, Auctioned by Spink, June 1987.
I did hear that the coin was once in the Royal collection.
I guess you spent a big amount of energy towards stacking direction and now you're having a time-out period. Don't think too much about that, I had had lots of times when I just wanted to sell everything and forget about stacking at all, but we change as time flows and our attitude and desires change too. so that's ok
