mystery 1988 Lincoln---what happened to this coin???

[port ewen ace]

found this in the reject tray. here are the stats:
center thickness- .0504", rim- .113", diameter- .717"
normal Zincoln:
center thickness- .0504", rim- .0505", diameter- .75"
the rim shows no evidence of hammering, the details are extremely blurred, the front and reverse rim surface has no copper plating, and the depth from rim crown to the field is uniform for both sides. weight is 2.5 grams. note the rim is "rolled" over the lettering on both sides. all opinions welcome, I have "no eye deer" what caused this

Kinda looks like someone valued it (maybe a child birth date, etc.) so they wrapped it so they could hang it from a necklace?

Looks like someone started tapping the edge to make a ring. You can roll the edge by repeatedly tapping it with a spoon. Attached image shows two coins in process.

Otherwise known as a dryer coin.......

could be anything

I am still unsure how a dryer could cause a perfectly uniform deformation of a coin while still retaining the smooth original contour of the rim with no impact marks, and both faces have identically blurred remaining details. as noted the weight and face dimensions are normal, only diameter and rim thickness are off spec. I will now ponder what would happen if the Michelin Man or Pillsbury doughboy were to be put in a dryer

That's just a term used for that type of coin damage. Like bradyboy mentioned, it could be from a number of machines that can roll a coin like that. It can be done deliberately by hand too. It's not a mint error however. Yours could also be a ground down zinc cent hammered into a silver ring too.
