Mike has seen and evaluated more errors than 1000+ of us semi-coin-literate old-timers like me. I, too, found my first error, a 1971 Lincoln cent struck-thru-capped-die, in 1986 in our large "penny" jar and, like you, I did not know what it was nor why it occurred. It took a lot of searching, in the days before the Internet (!) to figure out what it was. Between that day and the mid-90's I collected over 300 of this type error on Lincoln cents (Wheats and Memorials).
I even had a few progressions struck thru the same deteriorating cap, identified by die scratch/crack markers on the reverse. I sent a 7-piece progression to Arnie Margolis, editor and publisher of the now defunct Error Trends Coin Magazine, who photographed the coins and ran a "big" article about them around 1992 or so.
