In looking at silver railroad passes on the Coloradoartifactual site (see Otto Mears passes), they apparently included a card promoting that the pass was made from Colorado silver by native workmen. The passes themselves seem to be marked with a (native) maker in Santa Fe but have no quality indicators. They are reportedly made from a single ounce. It would seem then that the term Colorado Silver was in common usage refering to the source of ores but without specification of the guarantee standard. During the 1880's, Colorado was booming as a result of silver mining. The failure to get a national monetary silver standard, along with the financial reversals of 1892-3, apparently hit Colorado hard. Perhaps a surplus of ore and faultering market prices may have led to this attempt to push "Colorado Silver" as some kind of home grown product, sort of like the "Made in California" pottery movement of the 1950's. In short, nothing so far suggests that Colorado Silver is anything other than a true silver alloy...presumably falling within general coin standards at a minimum. Unlike D&A's Nevada Silver, this does not pop up on any list of proven false-precious substitute metals. [A.B.F. may have also produced items marked Sterling where that standard was met.]
