Rarity: Unique?

Variety equivalents:
Not listed in Newman or Kessler, Breen 1316

Notes:
This variety was discovered in 1979 by Anthony Terranova.

This was the only use of the obverse die.  MIND and YOUR are far apart, with no marker separating them.  The club-like rays have concave ends (Breen calls these "Musket Butt Rays").

This was the only use of the reverse die.  STATES appears on the left side of the label; UNITED appears on the right.  This is the only Fugio Cent variety that combines the the Club Rays, Concave Ends obverse with a STATES/UNITED reverse.
