            Item.of('econ:copper_coin', 9),
            [
                Item.of('econ:monetary_source',1).keepIngredient(Item.of('econ:monetary_source',1)),
                Item.of('minecraft:copper_ingot',1)
            ]
        )

        event.shapeless(
            Item.of('econ:copper_coin', 9),
            [
