There was a time when some marketing companies would get worn and oxidized "steel" cents and gray heavily circulated
War Nickels and have them plated or order them as such and put them in framed illustrated boards with WWII wartime themes for wall hangers. Just like some type sets, sometimes the heavily circulated silver coins were highly polished.
The people who sold these sometimes got honest enough to call them "reconditioned".
It appears you have one of these.
Of course this ruined what little value the coins had in the first place, but they looked "pretty" to buyers who knew very little about coins. My father had a couple in his office like this. Polished
Indian cents and polished no date
