Undated (January 1965) General Motors Roller Press Experimental Cent. Judd-Unlisted, Pollock-4055. Rarity-8. Copper. Plain Edge. MS-63 BN (PCGS). 20 mm. 72.1 grains. Coin alignment. <strong>Obv:</strong> "Lincoln Head" type with a portrait of the president similar to that used on the United States Mints regular issue Lincoln cent, with broad rim. <strong>Rev:</strong> Inscription MANUFACTURING / STAFF / DEVELOPMENT, for General Motors Manufacturing Development Staff, with broad rim. The obverse is that of Pollock-4055, but the reverse is unlisted therein; the <em>uspatterns.com</em> website refers to this die combination as "Pollock-4056." Beautiful rose-brown surfaces are richly and originally toned with a satin to softly frosted texture. There are few blemishes of note, and the eye appeal is strong.<p>As with the example above, this piece was struck from a spark erosion obverse die created by General Motors using an actual Lincoln cent as a model. It differs from the preceding specimen, however, in having wider, more uniform rims around both sides. These are also rounded except at the lower obverse, where the rim is somewhat flattened due to slight misalignment of the dies in the press. Struck during early General Motors testing on one of the first prototype presses. PCGS# 810951. From the Estate of a General Motors Technical Center Employee. Pictured on page 70 of Vol. 36, Issue 1833 of <em>Coin World</em>, May 29, 1995, and page 6 of (our) Bowers and Merenas <em>Rare Coin Review</em>, No. 107, September/October 1995.
