1875-CC Trade Dollar, T-1/T-1, NGC UNC Details/Stained

I'm still trying to figure out this coin as well as NGC.

Label says "UNC Details -- Stained".

OK, but where is it stained?

I've shown this to apprioximately 20 - 30 people and all are as mystified as me.

No stain, or stains, anywhere!!!   Go figure!!!

A pleasing coin with subdued luster and NO stains!

Nice, and scarce, in MS.

Looks like maybe an MS 61/62 overall.

Seen far worse @ $3000.

We're asking only $1775.
