CoinHi, rolling folds on clad coins never show the copper core dragged over onto the coin's surface. They also never show damage to the area that will become the design rim. This coin shows both.

I'm still puzzled. I've posted another photo showing the edge only because I think the other angle didn't show this effect well enough. The reverse clad layer has been dragged onto the edge obscuring some copper core. Back to the article "The rolling fold in this example lies on the face derived from the original upper face of the coin metal strip. We can tell this is the case because the reverse clad layer has been dragged onto the edge a little bit, obscuring some of the copper core. This effect occurs on all clad coins and occurs when the blank is forced through the hole in the perforated base plate." Couldn't this be an atypical fold instead?  |

Your photo of the edge changes my assessment. A rim burr should not affect the exposure of the copper core and should disturb the reeding, at least to some extent. So the balance of the evidence does support your contention that this is an atypical rolling fold. I'm always glad to be corrected.

Actually, this would make for an interesting column in Coin World. I'll just download your excellent photos and use them. I'll need your full name so I can properly credit you. Error coin writer and researcher.

My article on this Vermont quarter is now out in the online edition of Coin World (print to follow). I ended up agreeing with CoinHi that this is a rolling fold (blanking burr), albeit an unusual one. Error coin writer and researcher.

Very interesting assessment from Mike.
For me still an mystery where was happened in the production. I presume happened in the milling process. So if rolling fold happened, the milling will show and crack the molecular structure of the CU. If I see the coin face on the rim the material is broke. And on the reeds we can see the structural of the material.
COINH superb photos.
As I state before, this it is a very rare event in the coins production.

Thanks Rob & Silviosi! Quote:

It seems that these errors get lumped in with the more common pre-strike rim burrs so most people don't know the difference and so there is probably not the market for them that there otherwise might be. I would think an unusual one like this would be even more rare. Thanks again for orginally posting that article last month. It informed me of these errors and I was able to make this purchase, confident that it was an unusual error. Thanks for the photo compliment too! I was happy to see that Mike used these photos in the Coin World article. "Pride is yoked with callous behavior, as humility is with compassion."
