These three are plastic interlocking poker chips gold hot-stamped with the "Reddy Kilowatt" image on one side and "Reddy Kilowatt The Mighty Atom" on the other. These were promo chips for the electric power industry in the forties and early fifties when it appeared that nuclear power plants were to be the wave of the future for US energy.

If you want these three chips, PayPal me $10 and your address and they are yours. I don't believe they are in the Seymour antique chip catalog.
