will help you figure out which models you have. I wouldn't mind adding that unicorn stallion to my collection
. Please take price guides with a grain of salt. In this economy prices are very shakey. Ebay
has a section just for Breyer models. The ones you have are traditional size. Go under collectibles, animals, horses, then Breyer traditional to list them and get the most bang for your buck.
I am a collector with over 200 models, an BreyerFest attendee, and very active in the hobby and I have found Ebay to be the best way to get the most for my models. It is somewhat of a hassle, but right now you can list 5 items every 30 days without having to pay the listing fee. Good luck, and send me the link to the unicorn stallion auction
