Gold was plentiful in California after 1849, but coins small enough to make change were not. The United States Assay Office in San Francisco was at first allowed to strike only octagonal fifty-dollar pieces, and shopkeepers took almost any foreign silver coin of about the right size as a quarter or half dollar. In 1852 San Francisco jewelers began striking tiny gold pieces of 25 cents, 50 cents and one dollar to fill the gap. A New Orleans paper reported receiving a California gold half dollar in June 1852, and letters from the next few years show miners spending them and tucking them into envelopes for family back East.
The makers were mostly French jewelers. Pierre Frontier and Eugene Deviercy signed some of their dies FD; Antoine Louis Nouizillet signed with N; the engraver M. Deriberpie signed DERI or DERIB; and Gaime, Guillemot & Co. used GG. The Joseph Brothers were among the earliest producers. The trade had its rough edges: Dan Owens found that Deriberpie, Nouizillet and Isadore Routhier were arrested in April 1853 on a charge of counterfeiting the ten-dollar pieces of Wass, Molitor & Co., and all three went back to making small gold afterwards. When the steamer Winfield Scott was wrecked off Anacapa Island in December 1853, divers later recovered 51 fractional pieces from the passengers' luggage, among them six octagonal dollars of 1853 signed by Deriberpie.
None of these pieces held as much gold as its face value called for. Mike Locke works out that a full-weight California gold dollar would weigh about 1.71 grams, and no Period One dollar reaches three-quarters of that. Once the San Francisco Mint was striking quarters and half dollars in quantity in 1855 and 1856, the need for private change disappeared, and the French jewelers stopped. Collectors call these early pieces Period One; the first edition of Breen-Gillio ended the period in 1856, and the second edition carries it to 1857.
From the end of the 1850s jewelers took up the little coins again, this time for visitors who wanted a piece of California gold to take home. These Period Two pieces, which Breen-Gillio's second edition dates 1858 to 1882 (1859 to 1882 in the first), carry dates into the early 1880s, are lighter still, and were not meant to circulate; Locke reports a Mint assay that found that 1859-dated pieces held gold for only about a quarter of their stated value. Frontier, Deviercy & Co. carried on into the new period; Robert B. Gray & Co., which took over Nouizillet's business around 1859-1860, marked some pieces G; Frontier & Bellemere struck quarters with a head of Washington in 1872; the Levison Brothers' pieces carry an L; and Christopher Ferdinand Mohrig made many of the Indian-head pieces. Away from San Francisco, Reuben N. Hershfield and Noah Mitchell of Leavenworth, Kansas, put an H on their pieces of 1871. Some Period Two pieces were backdated, such as the Indian-head quarters and halves dated 1852 that were made decades later.
An act of Congress approved June 8, 1864 made it a crime to make or pass any private coin intended for use as money. The souvenir trade went on anyway. According to Wikipedia the law was enforced in a Boston case in 1869 and at Fort Leavenworth in 1871; a dealer note citing Robert Leonard says federal agents stopped the Hershfield and Mitchell pieces that August. At some point a Secret Service man paid face value to a jeweler for one quarter and one half to hold as evidence, and a Secret Service visit in 1883, which brought no charges, ended the denominated pieces: from then on the makers left the value off, producing tokens rather than fractional gold. Later still came copies of the old pieces, including those of Herman Kroll in the early 1900s.
