Could you tell me how much the ticket is worth ???

For the entry you give what you want up to 1 dollar, the values ​​it says (for example adult: $ 23 students, $ 18) are only suggested to enter whatever you want However there are special exhibitions which are corduroy to part, as would be the mummies. About the New York Pass, if you have access, in the brochure that you are given in the entry, specify it.

I took the New York Pass and with that you have a free access
