Does anyone know what is the weight tolerance for the Canadian 1 ounce gold maple leaf?

I have a gold maple leaf which weighs 31.22 grams. A troy ounce is 31.103 grams. Is 31.22 grams within the Mint's tolerance level, or not?

Thanks in advance for the help.

    Not my area, but i did some googling for you and here's what i saw being discussed in the past on kitko forums:

    There is a normal weight variation among coins due to manufacturing tolerances but they should always be overweight. For CMLs that are .999 they need to have an additional .1% to bring the minimum up from 31.10 to 31.13. The older ones I've tested all tend to be very close to 31.19.

    This one is a .9999

    Is your scale accurate to that level of measurement?

    Boosibri, you make a good point. I just recalibrated the scale, it measures to .01 grams. Other than recalibration, I have no way to know if the scale is that accurate (i.e., it registers to .01 grams, but it could show the wrong weight).

    Weigh something with your scale of a known weight!

    If it's one of the recent ones, it should be pretty obvious if it's a fake as RCM implemented a ton of anti-counterfeiting measures.
