No “CENTS” nickel
Those Liberty Head or “V” nickels struck in 1883 without a denomination. This was very confusing to the public and led to the “racketeer” nickel scandal in which gold-plated No "CENTS" nickels were passed off as $5 gold pieces.
No Arrows
Term applied to coins without arrows by their dates during years when other coins had arrows by the date. (Example: the 1853 No Arrows half dime and 1853 Arrows half dime.)
No Motto
Coins struck without the motto, “IN GOD WE TRUST.” This motto was mandated by an act of Congress and appeared on nearly every United States coin since the 1860s. (Teddy Roosevelt felt this was sacrilegious and had it removed from the newly redesigned 1907 eagles and double eagles. Citizen protests soon were overwhelming and it was restored in 1908.) This also refers to coins struck before the motto was added in the 1860s.
No Stars
Term applying to the Christian Gobrecht designed Liberty Seated coins without stars.
