I suggest you use eBay to get an idea. The value of a doll depends on several factors. One is the current state and shape of the doll and how well it has been preserved. If it has been played with or the original clothing is dirty, torn, or replaced the value is very little. Another factor is if there is a box and papers with the doll still around. Collectors look for boxes, papers, markings on the doll. If it is numbered . The number you give is not what is needed, but looks more like a stock number. Look on the neck under the hair of the doll and if there is nothing there you don't have a collectible. The collectible market is a little like the stock market the secondary price is based on what someone will pay for the doll and if it meets the qualifications I have all ready given you. The material it is made from is also important and when it was made. If it is still in production or rare makes it valuable.
