Thank you for your response Cubro99. I've always wondered about the surface looks of our post 1996 cents, when so many aren't smooth looking. The textured effects seem to vary in degrees, some a LOT, even within the same year. Some even look close to what I've seen called "rippled" coins (but not as severe as rippled photos I've seen)
The rest of this post meant for anyone and everyone, and is basically me just tossing out thoughts and things I wonder about. If anyone has any opinions or explanations, that would be great though
I read recently, as I think I mentioned, about zinc corroding easily (or something) and also read somewhere and saw some photos of "bumply pimply" surfaces with mentions about the planchet itself was corroded. Which would be UNDER the copper plating.
Am I to assume that in cases of corrosion that these coins minted smooth and then in time the zinc under the plating started eroding and created the stippling/bumps, striations etc? So that the surface GREW to become textured AFTER they left the mint?
(I also remember reading about some striations are a result of die polishing)
Or did the corrosion happen even before they were plated and therefore these coins left the mint "textured" ... and will the corroding grow worse in time?
I've already picked up a lot of info about cents mostly, in general, from varieties and key dates, to terminology, and ideas about the minting process, but so much to learn still. I'm sure a lot of other newbie people have a lot of the same questions as I do, so maybe this thread can answer to a lot of people
Another point I wonder about is if the texturing was not meant to be minted that way, but for whatever reasons, most came out textured somehow to varying degrees, does that lower the overall grades of coins? or is it accepted as "normal to the mintage" and doesn't add or detract from value?
So many comments and questions out of such a tiny woman hey?
