2009 Humbert Commemorative 2.5 Oz. Troy 999.9 Thous. Fine Certified Pure California Gold NGC graded Gem Proof UCAM. Reproduction of a $50 Octagonal Humbert Slug.
Humbert and the U.S. Assay Office would produce what became the highest denomination U.S. gold coin to circulate -- octagonal-shaped $50 gold coin-ingots, often referred to as "slugs." On the original pieces the reverse design appears as a series of concentric circles in the center, surrounded by either overlapping lines or swirls that create a diamond effect (as on the lettered edge pieces), or a series of wavy, concentric circles (found on the reeded edge slugs). These concentric circular lines are known to mechanics as "engine turning,", the design is similar to the web-like engraving in the vignettes on paper money or on watchcases. This Humber Commemorative Ingot uses a similar technique for the background, with the inscription on a rectangular tablet in the center denoting the year, the weight, and the fineness.
Estimated Value $3,700 - 4,000.
The Dr. Hesselgesser Collection.
