its a keeper not an error its damage the copper was removed somehow looks like corrosion and the steel/zinc is starting to show.
Sorry, but slow down and think before posting. 1944 cents were bronze - copper/zinc/tin alloy. There is no steel/zinc that could show. Looks like solder.
I did think just didn't exactly remember if they were steel,zinc or both . It is possible for it to show but a second look make me agree with solder.
Exacitically. You hit the nail perfectly. Someone had a momentary idea to create something and failed miserably.
If you advise o p it is not an error = nav.. if you advise the o p it is damaged = nav.. if you advise the o p it is corroded = nav.. may I ask your definition of keeper ?
If there is a peeling effect on the copper it would not be solder. Solder would settle on the copper not in it. With that being said and a closer look I too believe it to be foreign, most likely solder. Thanks for posting the coin.
Some previous posts here on Coin Talk have indicated that craftsmen would often use an old penny to clean the solder from the tip of their soldering iron and the OPs coin looks like it might be one of those pennies. BTW welcome to CT @Enaïd.
Possible for what to show? These weren't plated over a core that could show if the plating gave way. These were copper/tin/zinc composition through and through. You must be getting these mixed up with the modern cents, which are cheap plate jobs.
It's not possible because it's NOT steel, zinc or both! No offense, but you're new at this so you should just read and learn.
I'm not new at this just got a little confused and now understand it was around 1:00 at night when I posted now stop talking and quoting those post of mine!!! gezz you are 6th and hopefully the last one to quote my posts in this thread.
