Hi,
       There are many factors that determine what you should do with your
shell
collection.
       To sell it is really dependent on need for money.
       To donate it requires someone willing to accept it.
       All of these areas should be persued before the collection is ready to
be sold
or donated.
       Check with Gary Rosenberg at Phila. museum as to the acceptability as
a donation to a museum.
       Check with a dealer on the value of the collection if they would buy
it.
       Then decide on what you want to do with the collection.
