What to do with Grandma's seashells?

[gensearch]

I'm new here. We have a large plastic bin and a cardboard box of some of the most beautiful seashells that we have ever seen!!  Grandma identified some of them, but not most of them.  We would love to see them in a "loving home".  But we have no idea of their value or how to sell them.  We need help!!  We are in SoCal if there is someone nearby who could help us.  I don't want to keep unwrapping them and wrapping them (even to take pictures) as some of them are very delicate.
Some of the tags are:
"Tent Olive..Oliva Porphyria..W. Central America"
"Imperial Voluta...So Sea" "10.00" on back of tag.
"Murex Haustellium"
"Purple Limpet"

Thanks in advance for any help.
