Never seen before. The design is much finer than nowadays. Great coin. I have some proof 2015 Berlin COin show Kooks (not doing much yet)

i really don't know much about kooks proof though i saw it was finer than other queen elizabeth proof dollar with more or less same price range

That's a beauty!!!!
If it were not too expensive, I would have collected the back years!
Great job, @psychkrhoz!

it was priced at 35€ but the owner who knew me gave me a 5€ discount so its a win 😉☺
