Nice Lot of Three Large HAWAIIAN Cowie Shells, One Humpback & Two Reticulated. I'm sorry to say these rare shells like very hard to find now.  My brother and I collected these shells in Hawaii when I was a scuba diver for my submarine in the military, if these sell well I will be posting more, so keep watching.  They have all been wrapped up in storage since the 1980s and are in excellent condition.
