I think that there is a grail piece for every maker & that is what I would love to see. It would surely be fantastic to see a type of pyramid structure, what would be even more impressive though would be to have a text book built in the fashion of a timeline that would actually represent the history of this space and show examples of coins in the order of release. What a story that un-made book would tell!
I think a textbook by someone like MJ (choose who you wanna collab with) would be invaluable.
Also - names some Grails! I only have one - Squirrelbits bitoply first edition #1 with matching coin (shhhhhhhhh)
Btcc would be the 6 coin set (I’m a buyer for the 5 coin set if anyone has one!!!)
Casascius?
Mybits?
Alpen?
I like this grail piece for each maker idea - all just my opinion
