The Pacific Company gold dollar was believed to only exist as a pattern in silver until 1999, when a metal detectorist discovered an example buried in Bethlehem, Pennsylvania. A second specimen was properly attributed by numismatist Stuart Levine in 2002, after being misidentified as a gilt silver pattern for nearly a century. In 2022, a third example appeared, having been held by a family since the 1920s when it was pulled from the coin box in a San Francisco cable car. All known pieces are struck in debased gold (approximately.600-fine). Formerly known as (K-Unlisted) this item was cataloged as K-4 in 2025.
