The term is usually used in describing the back of a Jefferson Nickel. Many of the earlier years of production were not well struck, meaning that, even in uncirculated condition, some of the detail of the coin would not be visible. The feature most often missing are the lines showing the 5 (or 6) steps on the Monticello on the coin's reverse. A coin with "Full Steps" (that is, one on which all of the steps are fully and completely dilineated) will often command a premium price.
