Every $200 I have weighs just over 12 oz.Troy and the 1/4 pounders I have also weigh just over 3 oz troy each, I think if they are marked one pound or a quarter pound they have to have the weight ot the mints could get in serious trouble. As far as the $10, $20, $28 and $40 strikes go they don't state the weight and do vary a bunch.
