Comparison of Types III and IV of the 2¢ Triangle: Portrait
Oval
A More Ragged Inner Portrait Oval Outline
Type III
Type IV
The
outline of the inner portrait oval is relatively
smooth.
The
outline of the inner portrait oval is relatively jagged when
compared to the Type III..
This is a relative distinction
and must be considered along with other factors before making a
determination. Many Type IIIs have somewhat jagged inner portrait oval lines
and could be confused with the Type IV.
All the Type III examples are from the same scanned
stamp, plate number 146, and all the Type IV examples are from the same
scanned stamp, plate number 762.
