Should I dip this coin?

The coin attached is not the prettiest coin in the world with the speckled toning. Nevertheless it's in the higher grades and a brief dip in Goddards may improve its apperance.

Any thoughts?

Its clean enough, with mine it would be a soak in warm soapy water, a gentle brush with a ultra soft tooth brush, rinse of any hand grime then rinse again in cold water, pat dry and see how things look,  👍

I would dip it in Goddards for no more than 10 seconds, rinse and dab dry. That might improve it to some extent but I wouldn't then be tempted to dip again.

Hmmm, I vote for a bit less aggressive. My fave is clear ammonia, diluted 1:1 that haw worked well on CuNi or silver coins. Try it on some cheaper bits and think you will likely see....

I wouldn't call 10 seconds in Goddards aggressive!

My chemistry classes and background beckon, and they say, well that it is an oxidant that chemically further oxidizes the surface for removal of the top layers of the coin. Ammonia does not react with the metal surfaces so would in fact be less aggressive.
