Beanie Babies monkey and other animals are collectible for fun but do not demand very high prices. Try selling on the web for your monkey, or craigslist or perhaps you can sell at a yard sale. There were so many that were made that you can pick them up almost anywhere.
There are many places where you can sell your Beanie Babies monkey. Yard sales, flea markets, and collectors shows are a few options, but the best place to sell your beanie baby is probably on the auction site, eBay.
If you want to reach a wide range of buyers, then the best place to sell your Beanie Babies monkey is probably on eBay. One word of advice though is to include a detailed description and some decent photos of the monkey when listing it on eBay.
I think the best place to sell Beanie Babies monkey would be on EBAY. If you have other items to sell, take your Beanie Babies and other items to a flea market and sell. You can advertise on CRAIGS LIST or local newspaper. Ask your friends and relatives as well!
