No engraving is tied to a specific Plate they will appear each one at a time depending on how many Plates the player has found so far, with the ninth Plate found using the same engraving as the first. When each Plate is obtained in Generation IV, a different engraving appears on the back of the Plate which reveals part of the myth of the creation of the Pokémon universe. In Pokémon Diamond, Pearl, and Platinum, the 16 Plates known at the time are spread far and wide across Sinnoh, and an additional copy of each Plate can also be dug up in the Underground.

Pokémon Legends: Arceus introduces a Plate for the Normal type, the Blank Plate, as well as the Legend Plate, which allows Arceus to change its type at will when using Judgment, bringing the number of known Plates to 19. There are 16 Plates in Generations IV and V, and 17 from Generation VI to Pokémon Brilliant Diamond and Shining Pearl with the introduction of the Fairy type and the corresponding Pixie Plate. They boost the power of the holder's moves of the corresponding type, and change Arceus and its signature move Judgment to that type. There is one Plate for each type (except ?, though a corresponding Arceus form exists as an error handler). 1.9 Pokémon Brilliant Diamond and Shining Pearl.1.7 Pokémon Sun, Moon, Ultra Sun, and Ultra Moon.1.6 Pokémon Omega Ruby and Alpha Sapphire.
