      The determination of "stage" differs according to whether the coin
      was struck in-collar, out-of-collar, on-center, or off-center.

      In an in-collar cent, for example, a brockage would be considered a
      later stage if the brockage is expanded, distorted, and with only the
      columns of the Memorial represented. The ghost of Lincoln should
      grow progressively stronger through these stages.

      However, you can get a strong ghost of Lincoln juxtaposed with a
      sharp, fairly complete incuse reverse design in the case of
      a "clashed cap strike". In this error, a late-stage die cap with a
      featureless reverse strikes the reverse die directly, picking up a
      partial image of the Memorial. The next coin struck shows a first-
      strike brockage lying on top of a strong ghost of Lincoln.

      In an off-center strike, a first-strike brockage can be grossly
      distorted, and therefore resemble a late-stage brockage.

      An indent can sometimes show a strong ghost of Lincoln in the floor
      of the indent. The strike thins the overlying planchet enough to
      allow significant bleed-through from the obverse die.

      Back to in-collar strikes. If a thin, split-before-strike planchet
      happens to enter the striking chamber on top of a normal planchet,
      you'll get the appearance of a mid- to late-stage capped die strike,
      even though it's a first strike. That's because the overlying coin
      is thin enough to allow a strong bleed-through.

      If a thin, split-before-strike planchet is struck by itself, then
      sticks to the obverse die, and is struck into the next coin, then
      you'll have what appears to be a clashed cap strike, even though it
      is a first strike brockage.

      The take-home message here is that you have to carefully consider all
      relevant factors before tagging a coin with the label "early
      stage", "middle stage", "late stage", etc.
