The sublevels in order of increasing energy are s, p, d, and f. Within each sublevel, the orbitals are further subdivided based on their orientations in space.
An element with electrons in s, p, d, and f orbitals is cerium (Ce). Cerium has electrons in the 4f, 5d, 6s, and 6p orbitals, as it is part of the lanthanide series which includes f-block elements.
The U.S. does not have any "F" mintmarks. Only P-D-S & W for any coins.
