Today My wife and I found a 1911 V Nickel about 5.5" deep with our White DFX in between two trees. How much could it be worth and should I clean it? And with what? Also found 1946 Nickel. I plan on going back soon.
Try white vinegar to clean it. Let it soak overnight. Since it's not a real valuable piece and if you're not planning on selling it, clean it up all pretty-like so you can enjoy it. Try not to buff/polish or rub it. Let the light acidity of the vinegar do the work. Rinse well w/cold water.
