For your consideration is this wonderful COWRIE !!!! I am a collector, not a dealer. I do not know the grading system but the info that I receive w/these shells will be included, I DID NOT do the grading. This 93+MM dark beauty is breath-taking, ebay will determine it's current worth. This one is not graded but I feel and see no chips or growth lines, just GORGEOUS!!! There is a 6.00 shipping charge paid by the lucky winner. Glad to combine pstg. for more than 1 item. I am also glad to send internationally for an additional handling charge of 2.00 + the actual pstg. for priority international mail. No returns unless not as described and no returns on internationally shipped items sorry. Please don't hesitate to ask questions. Have fun bidding and good luck.
