Bizarre 1961 Lincoln Cent..Help!!

[BttleDiggerDrew]

Haven't been hitting the pennies much recently until today, purchased a box and into my third roll I found a truly odd penny. It is smaller than a normal Lincoln but it is very smooth on the obverse and reverse, yes the first thing that you would think is that its just a worn penny, but...the edges very raised and have no wear on them whatsoever...An error?

Will post a picture later, the wife beckons me..

Brockage, maybe?

Commercial washing machine wear, then a Dremel tool polishing.

Possible wrong planchet?

Is it the same size as a dime? If it's wrong planchet, it'd be an awesome find. Pics please.
