The egg method works on silver coins, but I’m not sure if it’ll have any effect on a shield nickel. A couple of years ago I posted how I cleaned and then re-toned a Barber dime using eggs. Hope this helps.
The cleaning and re-toning of a silver coin
It will usually just darken Nickel. Tends not to take on the blue/gold tones easily since Nickel is pretty non reactive. It just tends to darken the copper content of the alloy to an ugly yellow. With nickels what you end up with really depends on the contamination percentage of the copper.
