Launched in November 2020, Warhammer stores ran a promotion whereby if you spent over £60 ($100) in store, you were given a promotional coin (Usually based around the current faction being released) More recently you could also pick up a free miniature from the current range. If you managed to collect 6 coins you can also pick up a card binder to keep your coins in. Games Workshop has also released some promotional coins similar in style to the store coins - I have included them below for reference.
