There are cards that are so rare that they are titled "Holy Grails". In this video I not only find one of my holy grails, but a true holy grail from the 1990s. Precious Metal Gems are some of the most sought after cards, but there is something even more rare than these iconic cards. Baseball Gem Masters 1/1s were introduced in 1999 Metal Universe and are some of the most sought after and hard to find cards of the era. In this video I explain my process of finding one of these holy grail baseball cards why I think it is this specific player's best card ever.
