The 1874 comes from a relatively lower mintage of 700. It is quite common except as a high-end gem with brown color which is scarce. Examples with red-brown surfaces are also rather common with scarcity starting at PR65. Full red examples are even more scarce. Only rare if there are cameo surfaces. Look for attractively toned brown pieces or blazing red surfaces as those are the most desirable and are not too hard to come across.
