Not to be confused with Phoenix Precious Metals, Phoenix Refining Corporation was actually a New York refiner. Most of the ingots found today are type 2 as per the picture below. Iconic hallmark with a Rocket going through the O. These have been found in 1 oz commercial art bars, to 5, 10 and 25 oz+ pours. The type 1 is exceptionally rare and only a handful have been discovered in 5 and 10 oz class. The type 1 has only the rocket hallmark on the obverse with no name stamped.
