Hello, I am brand new to this forum and just wanted some help regarding a pin that has been in our family for 25+ years. It's the large 1997 Villainesses pin one of 500. However, this one is a Disney factory prototype that was not numbered. It does have all the right marking but the number is blank ( /500). Just wondering how I can determine a value for it. It is a very good condition. Thank you in advance.
