I have a large cent (Matron head) and I can't tell the date due to the crust/dirt. I can make out the last number which is a 0 and I think I see a 2 for 1820 but I'm not positive. I want to know how you pros would clean a large cent without making the coin un-gradeable or considered damaged by the coin collectors. Thanks!
