Baad Daata’s GC4Q1T5 challenge cache has necessitated the creation of some additional ‘mint’ caches. This cache will add at least one more to the prerequisite 25.
The Philadelphia Mint was created from the need to establish a national identity and the needs of commerce in the United States. This led the Founding Fathers of the United States to make an establishment of a continental national mint a main priority after the ratification of the Constitution of the United States. The Coinage Act of 1792 was entered into law on April 2. It proclaimed the creation of the United States Mint. Philadelphia at that time was the nation's capital; therefore the first mint facility was built there. The Mint Act also instituted a decimal system based on a dollar unit; specified weights, metallic composition and fineness; and required each United States coin feature "an impression emblematic of liberty".
