moneybags New Member Australia 27 Posts	Posted 04/19/2013 11:52 pm Hi out there, Part of last weeks odd collection. Done a little research. Question #1, Is this a Sintered or a Annealed coin? Q#2 is, If so does it have more value than it's face value? Face would be good because it'll look nice shined up. I don't know if it go's all the way through, a little tint shows between the roo's head & the star. Cheers Peoples.. Any info would be welcome? https://goccf.com/t/129067 https://goccf.com/t/77778 Edited by moneybags 04/20/2013 10:17 pm Report this Post to the Staff

moneybags New Member Australia 27 Posts	Posted 04/20/2013 11:58 pm Enworb whats with the joke? gold looks gold, silver looks silver, then perhaps you can tell me what the copper on the coin is or is not.Please enlighten me on annealed coins. Its not earth dirt or weathering as Sfitzernator thinks! not found in a park nor is it paint, then what is the copper on the coin? Cheers. Is this a piebald annealed error, where nickel and ,copper separate to the surface? cheers. Edited by moneybags 04/21/2013 12:10 am Report this Post to the Staff
trout1105 Pillar of the Community Australia 7096 Posts	Posted 04/21/2013 12:04 am These coins are made from an alloy of 75% Nickel and 25% copper. I would imagine that this coin has been exposed to a pretty harsh chemical that ate away some of the nickel and left the copper behind, or another scenario is has been subject to electrolysis and has become partly copper plated. either way it certainly looks like environmental damage to me Report this Post to the Staff
sfitzernator Valued Member Australia 271 Posts	Posted 04/21/2013 12:10 am Sorry, Moneybags, I drew that conclusion from your second pic. It looks a little corroded in that one. Report this Post to the Staff
moneybags New Member Australia 27 Posts	Posted 04/21/2013 12:20 am Thanks trout, do you think it could be a Piebald pattern annealed error? shiny nickel, shiny copper & a little brown? I am sure a Piebald pattern is still an improper annealed coin! Report this Post to the Staff
trout1105 Pillar of the Community Australia 7096 Posts	Posted 04/21/2013 01:18 am I have a 1936 penny in aEF with strange toning only on the reverse that I have put down to environmental damage. Report this Post to the Staff
moneybags New Member Australia 27 Posts	Posted 04/21/2013 01:35 am ok, does anyone have a similar picture of this type of coin?(my coin). I would like to compare photos? .If a blank was over heated in an annealing oven, doesn't some of the copper separate to the top? cheers.That's how it looks to me!

trout1105 Pillar of the Community Australia 7096 Posts	Posted 04/21/2013 01:55 am I think you need to look at this old thread it will shed some light on your coin https://goccf.com/t/122618&whichpage=3 Report this Post to the Staff
moneybags New Member Australia 27 Posts	Posted 04/21/2013 03:12 am sorry trout It is no pub coin not by a long shot. The coin is not corroded either. The thread all wrong! Not a pub coin or road kill or found in a park! I still have no viable or plausible answers? To shiny, non corroded and not damaged in a Mechanical sense, it looks way to organic to be tampered with to. I see green patina, nickel & shiny copper all through the heads side! There is something else to this coin. Can someone please think of a more plausible answer other than Pub coins, or buried in earth dirt. Floating separated nickel & copper due to extreme heat in oven. That looks more like the picture of the coin. Cheers peoples. Report this Post to the Staff
enworb Pillar of the Community Australia 4411 Posts	Posted 04/21/2013 04:38 am I thought the in your original post meant you made the coin go this colour an thats what made me think you were joking. Looks to me like you have a damaged coin, not an error. Keep looking for an error in it by all means but you aint gonna find one. Listen to what others have said. Report this Post to the Staff
sfitzernator Valued Member Australia 271 Posts	Posted 04/21/2013 05:09 am Regardless of the outcome, Moneybags, thank you for this thread. I just read through the entire thread that your first post referred to, and found it extremely absorbing! Keep asking, Keep questioning, and by all means, Keep posting :) Report this Post to the Staff
