I talk to a coinstar guy yesterday and he said the new machines coming out dont have the magnet and they fall into the reject tray in the front. But if you have crapy us coins they go into the tray inside the machine. He also said they dont keep silver it comes out into the reject tray in the front.
On an unrelated note, I was looking through my bag of foreign last night and decided to look up a 1975 New Hebrides 10 Franc coin that I found in rejects a while back. The coin looks uncirculated. Not sure how big the market is for the coin, but it looks like it could be worth anywhere between 10 and 40 bucks. Quickly put it in a 2x2 protector.
