enworb Pillar of the Community Australia 4411 Posts	Posted 08/07/2013 8:42 pm Looks like a lamination that hasnt come off. Almost identical errors are quite common on Australian predecimal copper. Report this Post to the Staff
jakedacc Pillar of the Community Canada 1177 Posts	Posted 08/07/2013 8:46 pm Being on a very key date penny, does anyone know the added value to the original price? Report this Post to the Staff

Almost nothing... being a key date actually minimizes the value of the error on low-grade key date coins.

Dteam New Member Canada 19 Posts	Posted 02/10/2016 2:18 pm There is mine... Gas bubble and flaw planchet + a strange a damage after It was struck without rim damage and without reverse damage. By the way, It was my filler but now It's more than that for me ! [/quote] [/quote] Edited by Dteam 02/10/2016 2:37 pm Report this Post to the Staff
Alexer Pillar of the Community Canada 2632 Posts	Posted 02/10/2016 2:47 pm Dteam - Thousands of coins have lamination issue's and yours is one of them. As for the rest of it I can't make it out very well..but looks like PMD from here. Did the king get a little rock embedded in his face edit by the way you should have started you own thread Edited by Alexer 02/10/2016 2:49 pm Report this Post to the Staff
SPP-Ottawa Moderator Canada 10458 Posts	Posted 02/10/2016 2:55 pm What's the story behind the watermark on those images?

Dteam New Member Canada 19 Posts	Posted 02/10/2016 3:24 pm I posted those images of my coin on another forum last year and I have tried to find an answer about the damage on the coin after It was struck. I would like to know If Its a Mint error . It's not a drill damage, It's not an impact. I don't know what It is. So I hope somebody have an idea. By the way, It's common to have a lamination issue, but two different kind on the same coin is special for me. Report this Post to the Staff
Alexer Pillar of the Community Canada 2632 Posts	Posted 02/10/2016 3:58 pm Quote: tried to find an answer about the damage on the coin after It was struck That would be anyone's guess..here's one.. It looks to me like the obverse was laying on top of a tiny piece of broken necklace chain with a tiny rock beside it on the road when it got ran over. Big rubber tire didn't hurt the reverse. what do you think? Report this Post to the Staff
Dteam New Member Canada 19 Posts	Posted 02/10/2016 4:23 pm Tiny rock ? It's a bubble in the copper before the striking process like this coins (see below). By the way, nice story Report this Post to the Staff
Alexer Pillar of the Community Canada 2632 Posts	Posted 02/10/2016 4:52 pm If its a hole like in the 2005 then why didn't you show us an angle picture of the coin in question, looking straight at it appears as though there is something in it. That 05 spent a lot of time in water somewhere by the looks of that toning. I could switch the story to fit the hole..lol Report this Post to the Staff
rocky Pillar of the Community Canada 2784 Posts	Posted 02/10/2016 6:58 pm Dteam I like to see your coin closer. have you done any research on how. the mint removes a jammed coin from a die. I have no idea how they would do that. but I have done thousands of presses of steel copper and aluminum. but I know when we had a jamup on the die. we used what we called it a pigtail. looks very similar to the mark on your penny. you see you slowly screwed it in along the metal. it slightly expands to push the die back. at the same time freeing the stuck sleeve. wondering is the mark thicker at the rim than in the center. if so that would be pretty close to what we used. wonder what the mint uses. they got to get hang ups. to bad some one couldn't go to the mint and find out. or else they have some kind of ejection system still might plug. just a thought Report this Post to the Staff
Dteam New Member Canada 19 Posts	Posted 02/10/2016 8:34 pm Thanks Rocky, A pigtail seems to be a nice hypothesis. I dont know If a picture of a mark of that tool on a coin exist, but for sure, I'll try to know more about that tool. Regards Report this Post to the Staff
rocky Pillar of the Community Canada 2784 Posts	Posted 02/10/2016 9:49 pm see my work was with wire. every thing had to be pressed at 50 tons same as coins. I can tell you in 1975 the press. I was on was a 2 man H press done by hand pumping. a long pipe pushed over a short handle we would do this all-day long. 6 man team 2 pumping the press at the same time. some times the dies would move a little. that when you got jams. that when this little tool would be turned in to force the die down and separate the metal. from the dies. I am quite sure in 1920s they had jams. see the metal on that coin could have jammed in the die. it would be interesting to know what there extraction tool looked like. I am think they had one. have a good one Report this Post to the Staff
