If your meter has .01 resolution it will display but the accuracy is still +-1 gram if it is %1 percent accurate. Considering this meter is such a low cost device and the manufacture has not speced this accuracy % it may very well be higher and 5% number would not be out of line.</p><p> </p><p>Not sure how this meter will effect the true weight of your coin(s) under test.
