All the figures, apart from the personal value that we give to them, being collectibles have a value in the market, this is very fluctuating and depends to a greater or lesser extent on the demand and quantity of existing figures. There are pages like Poppriceguide.com or Stashpedia that can give us an estimated value. These pages are based on the average of sales made on eBay. NOTE: if you find on eBay that someone sells X figure at a price, that does not mean that this is its value, ask, everyone can ask what they want, to know the real estimated value, look at some of these pages or do a search on eBay but filtering by sales made. That way you will see at what price they have really sold for. If you ask, for example, 1000€ for a figure, it doesn't mean that it is worth it or that it will be sold for that price.
