As coin collecting gained momentum during the early 1900s, the condition of a coin, along with its rarity, essentially determined its value as is the case today. And over the years, coin grading evolved to a system of finer and finer grade distinctions. The problem was the often subjective assignment of "grades" by different coin dealers.
Even after the Sheldon Scale of grading was introduced in 1948, the need for numismatists to agree on a universal standard remained. When PCGS was founded in 1986, the problem of standardization was solved - providing a reliable form of protection for rare coin collectors. In short, PCGS revolutionized the coin grading industry by creating an environment where consumers could participate in the coin market with confidence.
