One of 7 Gould Incorporated designs made circa 1978 as a replacement for the large Eisenhower dollar. For additional information on modern dollar patterns, see Mike Wallace's article on modern dollar patterns by clicking here. According to Roger Burdette in his book "Private Pattern and Related Pieces International Nickel & Gould Incorporated", these were struck on planchets that started with grooved edges and when struck were placed in a plain edge collar. Some coins still show the grooves but the intent was for these to have plain edges. This design was struck as folllows: Aluminum P5435 / RB1500 with only 2 or 3 known. Copper which is unlisted in Pollock. An example appeared in a bulk lot in Heritage 11/13 sale. We are calling it P5436 / RB1505. Brass which is unlisted in Pollock. An example appeared in a bulk lot in Heritage 11/13 sale. We are calling it P5437 / RB1510. Nickel P5440 / RB1515 with about a dozen known.
