2000-P Rosie annealing error? missing clad or copper core "migration"

[port ewen ace]

ooops---that be a 2010-P. found in a box a few weeks back. error-ref. makes note of this condition, either missing layer or faulty annealing causing molecular anomaly between copper & clad layers guess it beats 2499 skunk dimes

What is the thickness of said coin? It simply looks to me as if it was either tumbled with copper coins or had some chemical reaction. The design appears too crisp to be otherwise.

agree, Mike D. says environmental damage, again ---skunk on dimes continues :----(

It always gives me a warm feeling inside when Mr. Diamond and I reach the same conclusion! Means I'm seeing things correctly!
