EXTREMELY FINE APPEARANCE. A REMARKABLY RARE ORIGINAL-GUM EXAMPLE OF THE 1861 24-CENT STEEL BLUE.
The Steel Blue shade was produced early in the series of 24c 1861 shades, and it is scarce in any condition. Examples with original gum are rare, and those with Very Fine or Extremely Fine centering are of tremendous rarity, probably numbering no more than ten.
