massive shell collection for sale

[shellguy222]

This is my first time here, so I'm not sure how it works. The other day I was cleaning out my Dad's garage and I ran across what can only be described as a boat load of shells. Huge conchs, spider conchs and 50 other kinds I've never seen before. To me it appears that there are enough to start a small shell shop. Any feedback on what to do? Thanks much!
