Are the color designations Brown, Red Brown, or Red a judgment call on half cents, cents, and 2-cent coins or is there some standard a coin must reach to be identified as such?
Uncirculated and Proof U.S. copper coins are considered to be Brown if they retain less than 5 percent of their original mint glow, Red Brown if the original red color covers 5 to 95 percent of the obverse and reverse surface, and Red if more than 95 percent of the surface retains this original color
