Wrong denominations are coins struck on planchets intended for a different denomination.

            This category of wrong planchet strikes is still the most common. As a rule, only planchets equal or smaller than the intended planchets may be fed into coining presses and struck as coins. For example, it is unlikely for a twenty-five cents size planchet to be accidentally fed into a coining press and struck by dies set-up to strike ten cents size planchets. Within the limitations provided by this rule, there can only be sixteen possible combinations. The sixteenth possibility is a relatively new addition. Since the release of the reduced size circulating one dollar coin (The loon), it is now possible for a planchet intended for a loon one dollar coin, to be struck by fifty cents dies.

One Cent on a Ten Cents planchet. Twenty-five Cents on a Ten Cent planchet.
Five Cents on a One Cent planchet. Twenty-five Cents on a One Cent planchet.
