You have to be careful that you do not remove the patina from the coin. You don't want the bare metal to show. This is overcleaning and can make the coin subject to bronze disease and reduce it value. This coin and the last one you posted have been overcleaned a bit. It's going to take years for that patina to come back, unless you use chemicals to add a patina. When I first started cleaning coins I overcleaned some nice coins that still remain bright ten years later. I don't mean to sound harsh, I just want to pass on some advice to a fellow collector.
