john100 Pillar of the Community Canada 5324 Posts	Posted 06/25/2018 6:46 pm Picked up this odd looking penny for a lark at recent Torex show, had it XRF today 75% zinc, almost 25% copper and a touch of tin weighs 2.37 g just an ugly dark toned goldish colour. Is there such a 1979 brass penny ? Tried to match foreign planchets but nothing really matches Edited by john100 06/26/2018 6:45 pm Report this Post to the Staff

john100 Pillar of the Community Canada 5324 Posts	Posted 06/25/2018 8:52 pm According to a couple references, the 1997 penny is 98% zinc and about 2% copper, lost track of posting a pic, will try latter. The XRF was a rather large table top version at Canadian Coin and Currency goes to like 4 decimal points Edited by john100 06/25/2018 8:56 pm Report this Post to the Staff

SPP-Ottawa Moderator Canada 10458 Posts	Posted 06/27/2018 10:03 pm John100 - is the diameter of your coin slightly larger? The term " Texas Cent" comes to mind when I see stuff like this...

john100 Pillar of the Community Canada 5324 Posts	Posted 06/27/2018 10:36 pm Yes the penny has a slightly larger diameter, according to some references the 75% zinc 25% copper is known as Prince of Rupert brass or like a fools gold. Along with many other pennies I can see why this coin was pulled out, it is just weird looking, almost want to polish it, just kidding ! Report this Post to the Staff
