Unique single cards that are not particularly part of a set always have our interest.
Recent examples are the /250 Fire Cards distributed in 2021 Turbo Attax tins and the /350 Max Verstappen card handed out at the 2022 Hungaroring race in 2022.
True rookie cards do not always come from Topps or Panini. They can be part of a local card set or game early in the career of a (sports) icon. This happened with Luka Doncic who started his career in Europe. The only card featuring Max Verstappen with 0 wins was part of a Top Trumps card game “Grand Prix Heroes”.
