Xavier Roberts originally offered his Little People, dolls that evolved into Cabbage Patch Kids from his Babyland Hospital in the late 1970s. The originals were hand made and autographed or stamped with his name. Coleco bought the mass marketing rights to the doll in 1982 and changed the cloth face to a vinyl face.
The new Cabbage Patch Kids dolls set off a collectors frenzy. Before Christmas, people lined up outside of stores early in the morning to get hold of a doll before they were all sold. But as all booms must, it crashed as people lost interest. Coleco filed for bankruptcy in 1988 and the line was picked up by Hasbro.
Today, most CPKs sell for little more than the original price. You must remember that millions were sold.
The best value for is in the original pre-1982 versions. Robert's Little People dolls can command hefty prices. A few 1980s dolls in mint condition, in an unopened box, or with original clothing can command in the hundreds of dollars. Twins and dolls manufactured overseas (they were also produced in Japan, Spain, Italy, and West Germany) can also be valuable.
