I found an interesting 2000P dime tonight. Condition is AU-BU

Near the date, the rim is .0545, and on the opposite side it measures .0700. On the thicker edge, it shows an extra lip outside of the normal lip.

Is this sort of error worth looking into?

sounds like a mis-aligned die strike if the reverse is normal. They are not really worth any premium until the writing or design starts to come off the edge of the coin.

Thanks bman. It's not that far off, but it's an obvious error if you're paying attention. I'll toss it in with the other weird stuff I've found, and call it a day.
