The Closed 3 Variety from 1873 displays serifs on the 3 that are so close, it can be confused with an 8. Scarce only as a high-end gem with brown color. Otherwise, it is quite common. The same applies to examples with red-brown surfaces with scarcity starting at PR65. Full red examples are even scarcer. Only rare, in any way, if there are cameo surfaces. Look for attractively toned brown pieces or blazing red surfaces as those are highly sought after and not too tough to find.
