Pink depression glass comes in common pieces such as plates, glasses, goblets, cups, saucers, cream and sugar sets, pitchers, trays and cake plates -- it is the pattern that distinguishes it. Sought after patterns include Tea Room, Princess, Royal Lace, Miss America, Mayfair, American Sweetheart, Sharon and Adam.
Some patterns have been heavily reproduced, so it is always good to check for variations in color and texture to ensure that you have a genuine antique. Chips, cracks, etching and scratches reduce the value of antique pieces. Hard-to-find items in popular patterns, such as the American Sweetheart pitchers or the Sierra-Adam butter dish, can cost collectors upwards of $500 in the current market as of 2015.
