What was the purpose of the Lincoln Cent?

When the Lincoln Cent was introduced in 1909, it was discovered that the coining dies and their curved fields were unable to be polished to proof coining condition by existing Mint equipment. To produce Proof coinage for collectors, the U.S. Mint adopted the French technique of the Matte Proof, which was thought to highlight the design, while leaving the details of the coin as the designer intended. This was done by a sandblasting of the dies prior to use. When struck by the high pressure hydraulic press of the Philadelphia Mint Medal Room, the result was a semi-rough surface, a gentle luster and strongly defined wide square rims. These coins were produced in very small numbers, and the dies quickly developed small marks, known as diagnostics. These marks are used today by Third Party Graders and Collectors to authenticate the coin. Sold for mere pennies over face during the years of production, they were not popular with collectors. When new, the coins were wrapped in a tarnish-proof tissue, which over time proved to be anything but. Since many of these coins sat for decades unsold, vivid colors and toning developed. It is not unusual to see vivid blues, greens, lavender, coppery orange, deep reds and purple hues on these coins. Eagerly collected by numismatists today, they are among the most valuable Lincoln cents. Unencapsulated coins are easily identified by wide, square outer rims, quite unlike the rounded edges of business strikes.
