Noticed this penny this morning. I'm assuming this is a planchet issue, rather than, a die issue since the striations are on the obverse and reverse. It is also interesting how they cross the devices and even extend into the rim. I was trying to figure out how this happened. I think the striations are too uniform to be an alloy issue. Since the striations are perfectly parallel and run the same direction on obv and rev, I'm assuming they resulted when the metal was rolled into a sheet. To occur on the obv and rev in perfect parallel, I'm theorizing that the metal was "dragged" through fixed rollers, rather than being "rolled" (If that makes any sense). I don't guess the coin has any additional value, but I think is an interesting oddity. A true "Woody".
It's a interesting find, and I would keep it as well. But a "true Woody" is a improper alloy mix. I don't know if these are called anything other than roller marks.
Still a woody by definition. The different tones say that the metal wasn't properly mixed and softer in areas.
Thanks. Are these actual grooves or just surface discoloration. It is hard for me to tell, even under the microscope, but they look like grooves. If they are grooves, I would think they would have to be pretty deep to survive the striking process and remain uniform across the fields and the elements. Does anybody know why these roller marks don't get removed during the cleaning and polishing of the planchets?
They are not impressions in the coin, though they can appear to be. It is just surface grime mixed with impurities (dust, etc.) that rolled over them
