Interesting that much of the details are still present on your coins. For some reason they did not circulate as much as other coins.
That’s a fun part of collecting these...even stuff like that 1866 W/ Rays Shield Nickel above (probably a Good 4 or so) still show nice design details thanks to the dark/light contrast.
I don't have any circulated cams, but how about and uncirculated coin with toning that creates a cameo appearance. I used to own an uber cool Jefferson with Monticello in full cameo effect.
VERY nice!! Using your words, I hereby dub these : ToneCam : Uncirculated coin with toning that creates a cameo appearance.
My only purchase at the ANA show this year. The term "Circulated cameo" or "circ cam" seems to be becoming popular, as it was offered up several times as I showed it around.
