If there is the tag on it and depending on what generation the tag is. It is it can sell for $1,000 or more depending on the collector and how much they are willing to pay. I had one and sold it for $1,100. You can find out what generation the tag is online.
Do you still have the original tag on it. If not, it's price usually goes back down to what you purchased approx $10 unless there is a collecter out there who really wants it. You can always auction on ebay and see, but only if you're willing to part with it. I worked the Xmas Kioque years ago for Hallmark, and without tag, people were not interested.
