PA-224b. Pennsylvania. April 10, 1777. 4 Pounds. PCGS Currency Choice About New 55.The highest denomination from the issue and a very scarce type. All notes from this in red series are popular due the color scheme. The red face is very dynamic, but the back is printed in black only on this denomination. The Newman color plate note on page 54 of the fifth edition of The Early Paper Money of America. A very scarce type and one of the finest encountered by us.
