    How do I clean Bi-metal coins

    Can you tumble bi-metal coins and get them clean or does the difference in the two metals make that impossible. I am taking a lot of my foreign coin finds and am going to make resin drink coasters out of them and give as gifts to people from those countries but in the condition they are straight from the dirt they are hard to see any detail, so I wanted to clean them up. Should I just dry tumble them in a medium and not use anything else? Will be leaving to go shopping so I won't be responding back until later . Thanks in advance for responses. Also what type of medium would be best?

    How do I clean Bi-metal coins

    Wash them with dish soap and water to get the dirt and major grime off. Then use some Motherís Mag & Aluminum polish with a buffing wheel bit on a Dremel. You should get those shinier than the day they were minted.

    Obviously these are common U.S. clad coins, but this method should work on foreign bi-metal coins as well.

    I do that with the coin rings I make, But I am talking 300+ coins and I don't want to clean them one at a time. If that's my only choice it will take me forever Thanks for the idea though.
    I may have to hide a coin ring in a Fresno park and see if someone over there finds it.

    My computer is messed up I installed Windows 10 and it over rode windows 7 and my pictures go to 2 different spots and I can't upload pictures since except from my old pictures. I need to get it fixed. Mostly they have been out of clad quarters and Halves although I have done some out of Bi metal coins also. I'll see if I have any in my old picture folders.
