Is this a rolling fold error? Proof

jmcu12

I thought that this looked familiar to some pics I saw in an article by Mike Diamond in a recent edition of Coin World. I pulled this directly out of a proof set.

Thoughts?

The area to look at is in the left field just down from James' hair.

I believe it is a rim burr.

I say rim burr, others call it a rolling fold, so you are both correct.

What is the rarity for a proof? More or Less common?

Just by the nature of Proof coins,
with much smaller mintages, closer
examination of the planchets and
the final struck coins, Rim Burrs are
scarcer on Proof coinage.

That being said, I've seen a good number
of these on both Proof Manganese
Dollars and Proof States Quarters.

A nice find....

It's a rim burr. The fang-like shape is typical. It was probably torn up by the feeder finger. It's not a rolling fold (blanking burr). A rolling fold will assume the form of a low, broad, symmetrical tongue ot metal that protrudes a short distance into the field.
