Grail Booster Boxes #28 contains one of the rarest grail boxes we have ever used. This is a 2009 Platinum Arceus! This set was released during the era with the lowest demand for pokemon ever which meant extremely low production numbers. This was the introduction to one of the top legendary Pokemon which also contained Level X cards. These were the highest level of rarity at the time and the top cards in this set are worth as much as $50k and some of them have populations in the single digits in PSA 10 condition. We have also included the rarest box we have ever used, a Portuguese Diamond & Pearl Base Set released in 2007! We were lucky enough to get 2 of these boxes which are nearly non-existent through a large trade that we did with a very notable collector in Brazil.
