It's on their website. Adults, $10 | Seniors, Students, Military, Children 6-12, $5 Children under 6 are free. Museum Members are always free.
I think they're typically $10 for adults and $5 for students and children. You can also reserve museum passes for up to 4 people for free through the Brookline library!
You can get a membership pretty cheap too.
