B. Duncan of Columbia, South Carolina was one of several regional printers pressed into service by the Confederate Treasury — a consequence of having no established national printing infrastructure at the outbreak of secession. Duncan's output for the 1861 series is generally considered among the cruder lithographic work in the Confederate currency program, lacking the engraved quality that Southern authorities had hoped to source from Northern firms they could no longer use.

Cotton paper was a practical choice given the Union naval blockade's effect on rag paper supplies, though it created its own consistency problems across the run. Counterfeiting of Confederate notes was rampant almost immediately — Northern presses produced fakes in quantity, and Duncan's relatively simple lithography offered little defense.
