While the government’s response to the need for an adequate coinage was slow and never satisfactory, two institutions were established (the State Assay Office of California and the United States Assay Office) that did provide an unconventional and partly successful attempt to supply a frontier area with an acceptable quantity of an "official" circulating medium.

The private coinage proscription was not enforced by the public or government because the State Assay Office failed to mint enough ingots for the local demand. Ironically, an institution that was designed to replace the need for private gold minting actually preserved it (i.e., Moffat & Co.'s undebased coins from the first period continued in circulation) and in fact stimulated its resurgence (i.e., the second period of private gold coinage).
