Wrap cloth or other soft material around the coin, firmly hold it in a vice and bend to the required angle with an adjustable wrench, pliers or similar tool. The longer the wrench the easier and more precise the bending operation will be. You can also try tapping it witha hammer until you get to the angle you want. I've never tried bending 'silver' coins but copper ones bend quite easily. If they get bent too much, just place them on a solid flat surface, still covered with cloth, and tap them with the hammer until you undo the 'over bend' to your satisfaction.
