The Dollar Coin Converter is an annular attachment to a United States dollar coin, which semi-permanently converts the coin into a size that is tactilely and visually, more easily distinguished from the United States quarter coin. The invention also relates to correspondingly coated articles and to processes for the production thereof. For example, the capacitively-loaded magnetic dipole radiator may comprise a quasi loop with a tunable electric field bridge interposed between the quasi loop first and second ends. The pan also includes opposing upstanding handles.
