I see it as nothing more than baseless speculation. That heist involved silver coins as well but no silver was found in California. That heist took place in 1889 while there were a number of coins from the 1890s found in the California hoard. Most importantly, the ordinal distribution of the California coins negates any claim that it is tied to specific bank robbery of heist. The only way you are going to accumulate 50 years of dates and have them loaded in the cans in sequential order is to accumulate them over several decades.
