Both NGC and PCGS have slabbed such coins with a notation of "COPPER" and no notation on the slabs as to the types of borders. What warrants a "COPPER" notation and no notation as to types of borders? How can I identify one? The NGC coin census even lists these "COPPER" coins separately from the other 1860 Bun heads with border notations. The PCGS pop report lists them as Toothed/Beaded border. The best picture I have seen is on the NGC certification website for NGC #5897993-005 MS66. What are the borders on this coin? What should be a correct identification?
I am a new member and would very much appreciate help with this confusing issue. Thank you.
