So I was out with my Outlaw this evening and thought, light heartily, so if the disc on the Outlaw can separate a dime from a quarter, how about a copper penny from a dime? Laughing to myself I placed a dime and a copper penny down, passed the coil over both coins and by God it did it! I was able to disc out the copper penny and still read the dime. Unreal! Now, is it practical? Probably not, but the point is, the resolution of the disc on the Outlaw is outstanding and a testament to Tesoro's excellence. By the way, you can also separate a figure 8 pull tab from a nickle. But I'm sure that's no surprise.
