What would a softball sized hydnophora be worth?

I have this hydnophora that's about the size of a softball. I don't know what it might be worth because I got it as a trade for some bags of sand and other things at a frag swap.

$50 to $70

So, $60 should be a fair asking price? Alright. Anyone want a softball sized hydnophora for $60?
