Coral skeleton ID
 

I was recently given a piece of dried coral skeleton. Can someone please confirm for me if it is indeed a pipe organ coral skeleton?

It measures roughly 7" x 4". I don't have a SW tank to put it in at the moment so I'm not sure what I'm going to do with it. Are these worth anything? If so I might post it for sale.

It certainly looks like Pipe Organ. I read somewhere that they can be valuable because of the red colour of the skeleton. I can't remember where though. Wish i could help more.
