The Donner Party of 1846-1847 were two years ahead of the Gold Rush emigrants but were subject to the same financial constraints.
In 1891 two prospectors near California's Donner Lake found a cache of silver coins which had been buried by a member of the Donner Party in 1847, Mrs. Elizabeth Groves, nee Cooper, prior to her departure with the Second Relief Expedition on March 3, 1847.
She was too weak to carry the money. She died on or about March 7, 1847.
A list of the coins found is in the book
Numismatic Finds of the Americas by John M. Kleeberg.

And she carried only one of these with the date not known:
