So, I have accumulated a set from as early as 2005 Lincoln's that are toned is this Brilliant yellow tone. Is this another incident of a Brassy? Any Thoughts?
I have found many others 81 thru 83, some in the 90's. I chalk those up to chemistry experiments, these are still much more pl.
Color variation is common with Zincolns. Over time, the plating baths accumulate dissolved zinc, this causes a brassy appearance in the plating.
