BG-1301 is one of several fractional gold coins made by Herman Kroll sometime in the early 1900s. Kroll operated out of New York, where these were likely struck. No BG-1301s were made in California, nor did they ever circulate there, and they were made decades after the date on the coin. Nonetheless, BG-1301 remains popular with collectors due to its addition to the Breen-Gillio numbering system. 260 of them where discovered in 1923 as part of Kroll's estate after his death; they have all been widely dispersed. The original dies for this variety existed in 1968 and were later used to create restrikes (see BG-1301A). The "originals" are made of low-purity, red gold while the restrikes are a higher-purity, bright yellow gold.
