boba fett masked signed

Hi poocky2234. Thanks for your question. Fan-made items, while one-of-a-kind, tend to be worth whatever the creator wants to try to sell it for. For example, some art prints can sell for a few bucks or a few hundred dollars. The autograph is nice to have, and it cost something to get it, but in your case it might only add on a few more dollars than someone would pay for a home-made mask themselves. Good luck.
