What is a Grand Master Rare?
Grand Master Rares are individually numbered Yu-Gi-Oh! cards. The printed serial distinguishes one copy from every other copy in the same release, which means each card can be tracked as its own registry entry.
How discoveries are recorded
A discovery is supported by a photograph showing the card and its printed number. Confirmed submissions are then connected to the correct card, set, number and region while the original evidence photograph is preserved.
