I would cut it into 1/4s as soon as I got it to make sure it solid all through, and of course check the purity at my buddys pawn shop! It a true bargain for somebody to invest in at the present amount, credit wise is should hit at least 200,000
if you want to delete an item with no bids on it just go to that item & check the box at the top next to the edit box with the big X on it & it will end that auction, best of luck!
