NGC-graded California Gold Energizes Heritage US Coins Auction in October

Posted on 9/24/2018

Two NGC-certified rarities from the Gold Rush era are set to sell for six figures.

Two NGC-certified California gold "slugs" from the 1850s are bringing excitement to Heritage Auctions' US Coins Signature Auction in Chicago on October 11.

An 1855 Kellogg $50, graded NGC PF 63, is among the finest-graded of the 12-15 known survivors of an original mintage thought to number about two dozen.

Kellogg & Co. produced $20 gold "slugs" in 1854 and 1855 as the new San Francisco branch mint was still gaining its footing. It is unlikely the Kellogg $50 pieces were created for circulation, but rather to prove the company could produce the same kind of pieces a competitor was minting.

Meanwhile, another Gold Rush era rarity, an 1851 Humbert 887 With "50" $50, graded NGC MS 63★, is the finest-known example of this particular version of the octagonal ingots produced by US Assayer Augustus Humbert just a few years earlier.
