This is one of my favorite coins I've cleaned so far. I've preserved what little patina there was and it forms a marbling effect that I find pleasing. This coin soaked in distilled water for about 7 months and I only used toothpicks on it to clean. It really didn't require more than just some patience. Attribution was easy RIC I 116 it was minted in Rome around the year 50 and has the bust of Claudius who is considered one of the 12 great emperors of Rome. The reverse depicts Minerva (Athena) which is one of my favorite Roman gods. All around a great coin and its one of the gems of my collection.
