In 1889, it became law for miners to be certified "competent" in order to "prevent the employment of incompetent persons as Miners in Anthracite coal mines." This is a copy of my great grandpa Rudolph's "Anthracite Miner's Certificate." He worked in coal mines in Schuylkill County, Pa beginning in 1868, at 6 years of age, until 1933, when he was 71.
