1890 Liberty Head Quarter Eagle. Proof-67+ Deep Cameo (PCGS). CAC.，This superb gem boasts thick mint frost covering Liberty, the eagle and all stars and lettering. Placing the coin under a light and using a strong loupe reveals surfaces as close to perfection as one could possibly hope to acquire. The coin here presents a graduate course in quality. The fields are boldly mirrored by the dies, with the slight orange-peel surface quality created by heating the planchets prior to striking these coins-which appears when the coin is tilted under a light, so the perfectly smooth surface has what appears to be a fine texture beneath the glassy-watery fields. This combination of frost and mirrors produces a coin of extraordinary beauty, far and away different than a mint state product. The degree of contrast to create the Deep Cameo coinage of this era was perfected during the 1890s, when the greatest number of these visually remarkable coins were struck. An absolute prize worthy of the most advanced collection.<p>The total Proof mintage for the year 1890 was a mere 93 pieces of which perhaps half are known in all grades today. Gems are the most prized, and with fewer coins seen as the desired grade ticks up point by point, opportunities to acquire coins finer than PR-65 are few and far between. The present coin is the finest among all of them. For perspective, there are three grading events at PCGS at MS-66, one at MS-66+, two at MS-67, and then this piece with no rivals. If the best is what you require, here it is.<p>，PCGS# 97916. NGC ID: 288D.，PCGS Population: 1; none finer.，
