Like most collectible merchandise, Star Trek memorabilia is worth however much someone is willing to pay for it. There is no fixed price, just a general ballpark figure based on the rarity of the item. If you do possess something that you feel is of value and would like to find out how much it may be worth, we would suggest you try one of the online auction sites like eBay.com. There, you can either sell your merchandise or at least get an idea how much a similar item is worth if you wish to sell it by other means. On the other hand, you may just want to keep it!
