Assuming that all faulty coins weigh the same:
If you take 1 coin from the 1st machine, 2 from the 2nd, 3 from the 3rd, 4 from the 4th ect. Weigh the entire pile. If all the machines were working you should get 55g. Lets say that faulty coins all weigh 1/2g. If machine 1 was busted there would be 1 faulty coin. The total weight would be 54 1/2g. If machine 2 is busted there are 2 faulty coins in the mix. The total weight would be 54g. And so on....
Edit: I diddn't see maryter's post saying how much the faulty coins weigh. My solution still works for his faulty coin weight though.
