Estimation can be a useful tool for a team to do to ensure that everyone has a shared understanding of a task. Two drastically different estimations can highlight that there may be a lack of understanding or a high difference in skill / experience on the team. Knowing that allows empowers the team to break a task down smaller, make the task more clear, or spend some time educating team members. I don't think those estimates should be shared outside the team.
