Price of 30 lb Copal Stone

Last year my family found this stone on a beach in north Florida. After some testing and research it turned out to be copal.

Does anyone now how much it would be worth? Or if this type of thing would be right for a museum?

Any help on who to contact about such a thing would be appreciated as well.

Also if there is a better category for this question to be in please let me know that as well
