1852-dated 900-Thousandths $50s were struck at the United States Assay Office between October of 1852 and February of 1853. The denomination was then discontinued, most likely due to an increase in seignorage charges on $50s. Somewhere between 100 and 150 examples of the K-14 are known today, with around 15 known in mint state.
