As @spirityoda and @coinquest1961, I have a 2000 10c with that incredible doubled die, and I think it's my favorite variety. But I found a 2005 10c which has DDO that no one has reported a variety to that year so far. There is no mention of that kind of error to this year. I think I'm the first. I have another coins from Brazil with some errors. 10 centavos 2001 - DDO 1997 1 centavo Brazil - DDO (centavo) 1997 10 centavos Brazil DDR 1995 50 centavos Brazil - DDR 2008 10 centavos Brazil - CUD on obverse 1871 200 reis Brazil Delamination 1874 V Reis Portugal - Variety "foot on 4" reverse (No V) 1919 20 cents struck on 1894 20 cents Italy
