NoooOOooo....DO NOT CLEAN IT! Conserve it! That coin looks to have good detail, around VF-EF. If it's an EF coin and the corrosion hasn't completely destroyed it, it's close to a $200-300 coin. At minimum, it's worth $20-25 as it stands.
Electrolysis, peroxide, acids, etc. are FAR too harsh and will destroy any numismatic premium. Don't rush to ruin this coin! Always start gently and work your way up! First off, soak the coin in distilled water for a few days, if necessary, change out the water a few times as it get "gunked up". Report your progress here after you've completed the soak, take some pictures and we'll go from there.
