i am so overwhelmed with all your responses. This blog gets hundreds and twenties of thousands questions per day. If you could go back and read previous comments it should cover it.
You can also do a search on eBay for example and modify search to items sold. Type the name of beanie baby you have and you will see the average price of that item that has sold. This is the easier way. Otherwise I will do my best to reply to as many people as possible.
I do not give prices to new beanie babies, only retired. New beanies are worth about the price you paid.
