Please Help me identify this shell

[tjfm]

Hello everyone!

Please help me identify this shell given by my grandma. She was a collector of shells before and this one is separately and neatly boxed in her closet drawer, so i suppose this is a different kind. She passed away already and wasn't able to ask the name of this one, and how much this one costs.
size is about 7inches H x 4.5 in W
Thanks for all the help!
