What weighs 352 grams?

I can tell you now. 100 1p coins weigh 352 grams.
I had lots of 1p coins to count, so to make it easier I counted one bag, weighed it, then just put lots of coins into an empty bag, weighed it & added more or took them away to weigh 352 grams.
Things you do when you are short on money, lucky I had saved all these 1p's, I counted £11 worth & ran out of bags.
Now to put them into the Bank.
