Lingo for "Q"
Short for a coin of the quarter dollar denomination.
Correct terminology for a two-and-one-half dollar gold coin. This denomination, two and one half dollars or one fourth of an eagle, was first struck in 1796, struck sporadically thereafter, and discontinued in 1929.
Term to describe the color on a coin that may not be original. After a coin is dipped or cleaned, any subsequent toning, whether acquired naturally or induced artificially, will look different than original toning. PCGS will not grade coins with questionable color.
