Just received this Marcus Aurelius denarius .. (sorry for the large photos - got to fix that).. not the best example but I am happy to own it. Looking at Wildwinds I am thinking it is RIC 215 ..Sear 4888. However the example on that site states a weight of 3.68 grams. Mine is 2.56 grams. Is there a rule of thumb on tolerances? Just looking to learn from your experience. Thank you for any replies.
