The 1849 California One Dollar Patterns, also known as die trials, were created during the Gold Rush period as experimental designs by engraver James B. Longacre. These coins were struck to evaluate potential designs for new currency reflective of the wealth generated by California gold. A very limited number of these patterns exist, making them highly sought after among collectors due to their historical significance and rarity in American numismatic history.
