Dank has made public guarantees that he is soon to be one of the most famous and well known musicians in the world. The value of a personalized performance and recording from such an artiste early in his career is vast.
It's like having your personal recording from Jimi Hendrix singing happy birthday on your birthday party! It would only add to the value that so early in his career Jimi was sub-par on the guitar and also slightly out of tune. Collectors would go berserk but I imagine having such a piece would be emotionally too valuable for you to sell for mere millions of fiat money!
Yes, it would indeed be a prized collector's piece.
