Repeating digits or numbers in the pi number are the most important criteria for rarity. Based on this logic, we created a detailed rarity map under 27 categories. Any piece in the collection may have one or more of the categories we have explained in detail below.

By examining the cards below, you can see which category is prepared according to which feature. As you progress from Category-1 to Category-27, the rarity level gradually increases. for example, there is only one item in category 27th Which makes it one of the 2 most valuable pieces of the collection. The piece in the 27th category contains a sequence called the Feynman point, in which 6 consecutive 9s come together starting from the 762nd digit of the number pi. The Feynman point is named after the famous physicist Richard Feynman.
