should weigh 26.73 grams or just under....very little wear on it definitely not two and a half grams of wear. Magnet test not really trustworthy unless you have an earth magnet. Any pawn shop or coin shop will test it for free. If it is real it is worth a minimum of a hundred and twenty five dollars in any shape up to three grand...wouldn't sell it on Listia for twenty one dollars for sure.
