I posted similar wording for this coin in the grading section:
It appears very nice under all that junk pasted on the patina.
Plus I don't know if graders would take away or detail a grade for crud that possibly appears not to have etched into the patina.
What would be the best course of action considering time spent, value & ROI?
What are some proven methods/chemicals to use for this exact type of growth?
If there are similar looking nickel coins' before and after-cleaning shots, please post a link.
