Two-Face's Lucky Coin: kezako?

With the release of the set 6864 Batmobile and the Two-Face Chase, we are going to get a new minifigure of Two-Face alias Double-Face.

This minifigure has an accessory that intrigues some and delights others: the famous Two-Face's Lucky Coin, the silver dollar that Harvey Dent uses to make his decisions.

One side of this coin is just normal, the other is torn. If the lacerated face comes out, Dent will do the harm around him and his evil side will take over. If the other side comes out, it will behave correctly and will not commit crimes ...

This piece is already listed on Bricklink under the name Flat Silver Tile, Round 1 x 1 with Two-Face Corner Pattern (98138pb05), and has already been seen in other colors especially in some Ninjago sets.

The author of the review on FBTB adds that he was even entitled to two Coins in the set's inventory. The presence of this second Coin will it be systematic? It will have to be checked over the course of purchases and reviews that will appear online.
