Lot of very old Whelk seashells from NC. Most people call these conch shells, but from what I understand these are called Whelks. That is what they have on the NC coast. I got these from some elderly people who live on the coast and search for these themselves. I am not a shell expert, but that is what I found out when researching the proper name for these. Nice for decor or crafts. Thanks for looking at my items and have a great day.
