Official Pokemon Flip Coins

The official Pokemon TCG League rule on flip coins and their usage reads as below:-

Coin flips that land outside the playing area (off of the table or in another game's playing area) are considered invalid and must be flipped again. Once players have agreed on the result of a coin flip, it cannot be redone. Once a judge has ruled that a result is conclusive, it cannot be redone.

Titan Cards offer a wide variety of Pokemon TCG flip coins spanning many expansions and series.
