Ex American collectors find. It weighs approx 114 grams & is 4.3cms in diameter. No other history or date is known about the item other than the fact it was found with other Native American artifacts that has sticker on them with the name James Kellor. From the little research I did, I found that a James Kellor was part of the Glenn A Black laboratory, Indiana University. NOTE: Photo’s were taken with a flash to highlight the details.
