Sweeney's Coin Trick

You flick your wrist, causing one object in your hand to vanish. The object is transported to an extradimensional space, where it remains for the duration or until you fall unconscious. Only you can be holding the object, it must be non-magical, and can weigh no more than 5 pounds.

Until the spell ends, you can use your bonus action to summon the object to your free hand, and you can use your bonus action to return the object to the extradimensional space. An object still in the extradimensional space when the spell ends appears in your space, at your feet.

At Higher Levels. When you cast this spell using a spell slot of 3rd or 4th level, the duration is extended to 8 hours. When cast using a spell slot of 5th level or higher, the duration is extended to 24 hours and the object can be magical.
