Mint in box-complete, perhaps some age wear, but unplayed with, $175 to $300. Mint-excellent condition non boxed in all original clothes $60 to $150. Played with, very good condition in partial original clothes $25 to $75. Played with, well loved, no original clothes $10 to $40.

The doll and its accompanying accessories were advertised at less than $20. In 1961, the red Chatty Cathy dress was discontinued, replaced by a pink and white striped dress with a white pinafore called "Pink Peppermint Stick", which was available until 1964.
