Liberty Silver Dollar 1900

Hello,

This is a 1900 liberty silver dollar. Does anyone have any idea how much it is worth?  I don't see a mint marking, but I may be missing something.

Does anyone have information on this item? We are doing a class project in our seniors computer class to learn about all of the different resources to appraise our items, and learning skills in uploading photos and networking with others online.

Thank you!
