10 Centavos continuous legend, small letters

Colombia's shift to nickel-clad steel for this denomination in the early 1970s was driven by rising raw material costs and pressure to modernize the coinage infrastructure at the Bogotá mint. The "continuous legend" variety — distinguished from its predecessor by the unbroken run of lettering around the rim — emerged as part of a broader standardization effort and was minted across six years with relatively little variation between dates.

The small-letters designation separates this type from a parallel large-letters variety, a distinction that matters more to type collectors than casual accumulators.
