Suffix

In numismatic grading, a suffix refers to a letter or series of letters that follow the numerical grade of a coin, often denoting a physical feature of the coins strike or condition. In copper, examples would be RD (Red), RB (Red-Brown), and Brown (Brown), referring to the color. Another example would be "FB", indicating the coin has full-split-bands.
