The rarest card in 151 is Mew ex (#205), a Hyper Rare.
Why Mew ex tops the list
151 prints just 3 Hyper Rares, the thinnest tier in the set, and Mew ex sits at #205 among them. Rarity and price don't always line up. By market value the priciest card is Charizard ex (#199) at about $492.20, so the rarest pull and the most expensive one are different cards here.
