Hi I'm melissa I have penny that is about 1/4 or so of the corner and only 1/4 or so of corner on the backside as well it don't show no date on it it appears to show only untied states then the of is real small then it's cut off from there the it shows about 1/4 of the white house and appears to have under the united states the words E-Pluribus .unum. That is what the backside looks like then the rest of the back is just blank the color as if it hadn't been stamped. The front side of the penny is of this.....the what is supposed to be the penny front is stamped on it 1/3 of penny in the corner same on back side but anyhow it appears to show the liberty word and the shoulder part to only 1/3 of the face. It appears to look like the stamp was 1/4 off on the penny.
It does sound interesting, but posting good clear pictures of both sides of the coin would allow us to observe and discuss your coin.
