It is a little contest but the winner will get one GMB paid for by me.
Guess the weight in Grams, you can be under but not over and for the Americans there is 31.1grams in an Oz.
You are guessing how much gold i wear on a daily basis, if your not sure what a GMB is well let me tell you, it gives you an upvote for life from @goldmonkey , the contest will run until post closes and closesr without going over wins.
