"leads" (actually made of graphite) in pencils. The hardness
scale, from softer to harder, takes the form ..., 3B, 2B, B, HB, F, H,
2H, 3H, 4H, ..., with the standard "number 2" pencil being of
hardness 2H.

- In 1996 the government starting adding new security features to our
paper money due to the advanced copying technologies that have raised
the incidences of counterfeiting. The $20 bill entered circulation on
October of 2003, followed by the $50 in September of 2004, and then the
$10 in September of 2005. Subtle background colors have been added along
with other features to discourage counterfeiting.
