Okay, so you have some coins. Your not sure what they are (they are uncleaned after all), or how to go about finding out what exactley they are! We'll hopefully I can shed some light on what has worked for me. Not an expert by any means. But I'll try to layout as clear as possible what has worked, and has not. And some of my thoughts and observations. Some of the info will be from others and I'll try to not that.
