Help identifying found shells

[geraldide]

Hi
We were cleaning out the basement of the home we recently purchased and came across a box full of large and beautiful shells. I recognize a few of these shells types, but would like your assistance in identifying them.  Also if you have any thoughts on their condition/value, please let me know.
