SEarching my rolls today I found a silverish penny, a 1984D, thought it was another Lamination error as I have found a two before that the copper was either removed or missing, but this time, the coin is very light to the feel and has the Oxide layer on the silver color, I don't have a scale capable of weighting to the hundreds today, but perhaps I will get it soon. but any ideas how to tell what's happened here? Any ideas? the sound of it hitting the table sounds similar to the zinc ones, so maybe it's not aluninum? Dr.P
I'm not convienced that it's aluminium. Zinc are often more greyish then what I do happen to see unless there is too much lightening there. Alternatively it could be copper being stripped and then plated with another layer of metal but I can't quite tell what it is.
That looks unusually shiny for a cent missing the copper layer (usually the zinc oxides easily, turning it a dull dark grey). Who knows what might have happened to it though, try weighing it.
It has the appearance of a coin that has had the copper removed by acid - which would explain the low weight.
Foreign coins where minted in the United States mint until 1984. The foreign coins minted in 1984 where from Panama. half balboa quarter balboa 10 centisimo 1 centisimo All where minted at the Philadelphia mint. Lou
Yes they where. Denver, San Francisco, West Point and Philadelphi. Dever minted coins for the Philippines. Lou
maybe the planchet was left over from the year before, or the coin was minted in the later part of 1983
I've got the same thing but with some traces of the copper still there. I'm just wondering where the silver coloring comes from. These scans may not be the best, btw...
it's a regular copper plated Lincoln cent that has been to a high school science class. i have a few that have been dipped in acid to remove the copper. luckily they weren't variety coins - that would have made me cry. -Steve
yes, there is a ton of lightening, I think it's zinc not Al, but I will get the scale tommarow at work I have one there my postal scale doesn't show the difference. it's actually very gray when just looked at, also seems to be very detailed in terms of the surface and details, so i am not totally sure if orgaionally had the copper and was removed..
