1975 penny ? lamanation error or die clash

I had this coin in my collection but have never really looked at it until today. There seems to be a lamanation error all the way around the coin, most of the lettering looks like the coin was poured instead of stamped all messed up. Any ideas on it?

Don't see any signs whatsoever of a die clash. In my experience the edges of lamination errors where the planchet metal is separating are crisp and sharp. It always harder to tell from a photo than handling the coin but the devices (letters, date, bust, etc) just look like heavy wear or perhaps exposure to some sort of solvent rather than any die related issue, though I suppose it could have been struck by worn dies.

I have plenty of wheaties from the teens and twenties that have the same sort of look to them as far as the wearing on the devices go.

Trying to figure this one out? (The mushiness of the details could be an important clue.) Did this coin go through a tumbler, or did it get just a surface clean up by hand?

Neither that I know of I have had it for a long time. When I see a coin that has something different about it I have a box I put then into. If you can see the seperation between the rim & the bottom of the lettering of one cent, that goes all the way around coin.

Weigh the coin. Missing metal might indicate excessive wear, etc. Copper pennies aren't clad, i.e.: they are punched from a sheet of homogeneous metal so there is no "lamination" as with clad dimes, quarters etc.

Another possibility is that the design was punched through a thin sheet of something that blurred the details. But where the blurriness is on both sides I would think this is unlikely.

I'm going with missing metal. Saw something similar when I used a copper penny for an anode in an electrolysis bath. Straight up acid is a possibility but copper is pretty resistant to most acids, though nitric could do this rather quickly.

If the surface isn't pitted it tends to contradict the idea that the coin was corroded naturally then cleaned.
