thingee Pillar of the Community United States 2177 Posts	Posted 05/21/2007 12:27 pm Okay. I've posted these pics before and I want to educate myself on these errors. Now I know the first pic is a die crack as I've been told. Image Insert: Is this second pic also a die crack. The differences is that the second is not jagged like the one above. It is raised but more smooth and rounded. Also someone please tell how the second error was made opposed to the first one it is more rounded and smooth than jagged.

SsuperDdave Moderator United States 23522 Posts	Posted 05/21/2007 3:39 pm The first pic is a die crack - the die actually broke during the process of minting. The second pic is more likely a die gouge - something foreign hit the die at one point, cutting a straight gouge across it. Although it's not unheard of for a die to crack that straight, a gouge is more likely. Report this Post to the Staff
Metalman Pillar of the Community United States 7123 Posts	Posted 05/22/2007 11:18 am Hi Thingee check my email to you !! from a few days ago ,, the second coin is not a die crack but is trapped air between the zinc and the plating ,,it is a relitively common occurance on the zinc cents. Like I said in the email ,,I have a fairly large assortment of them ,,I think they are intersting although they add little or no value as an error. Metalman Report this Post to the Staff

coppercoins Pillar of the Community United States 7629 Posts	Posted 05/22/2007 7:15 pm The 1995 cent is the result of impurities remaining on the zinc blank before it was plated in copper. Gas formed under the copper and pushed it outward. The difference is easy to see, the first image is of a jagged line with very sharp edges - die crack. The second image is a straight line with soft edges - gas bubble. Report this Post to the Staff

I spend so little time with clad coinage, that thought never entered my mind. Well, that's why he's Coppercoins, and I'm not. Report this Post to the Staff

thingee Pillar of the Community United States 2177 Posts	Posted 05/27/2007 5:04 pm So whenever I see something like on the 2nd image, the 1995, it is specifically called a gas bubble error. The first cracked image is a cracked die. Thanks so much. This really helps a lot. Report this Post to the Staff
Metalman Pillar of the Community United States 7123 Posts	Posted 05/27/2007 6:21 pm Thingee in most cases the trapped gas forms in a fairly straight line , while die cracks have a much more archaic appearance. Im pretty sure that coppercoins can explain it better ,,but I try ! But essentially your take is correct !! and you can always ask here if your in doubt !! Metalman Report this Post to the Staff
