denny7000 Pillar of the Community Canada 1018 Posts	Posted 03/07/2017 6:56 pm Yes I saw that in Charlton so I weighed a few others of same dates and they all ranged from 3.15 to 3.27. I would guess it would depend on amount of wear, they are circulated. It also shows that the mint pounded out a lot of pennies in these two years. Report this Post to the Staff
TerryT Pillar of the Community Canada 822 Posts	Posted 03/08/2017 03:43 am Cool ! Looks to me like all the stretched-look does not affect the raised details, so something or someone made a twisting, grinding circular mark on the die (the fields of a coin would be the highest part of the die, the raised part of a coin is lowest, incused into the die). I think maybe the marks were on the die before the coin was struck. Report this Post to the Staff

Crazyb0 Rest in Peace 10197 Posts	Posted 03/12/2017 7:38 pm Put me in the trail die camp. Don't see a capped die at sll, even a late stage. The cap planchet would have to be so very thin or completely missing for the detail to transfer as it has in this manner. After reading this:http://www.traildies.com/the-theory...l-formation/ I was impacted by the statement that traildies impact at least 10% of the surface area but NEVER 100%. Too much detail is unaffected on these examples, meaning altho these lines cover more area than the common trail die, they still "Trail", note the 45 degree angle trails on 79 1 & CENT then trails around date There's some trail dies, looking at 78, same thing. Just shows how you Canucks wring every available drop out of what you have! Report this Post to the Staff
TerryT Pillar of the Community Canada 822 Posts	Posted 03/14/2017 02:50 am I imagine that a type of metal lathe was used in 1978-9 when making dies. It looks to me that the marks on the 1978 could have been left by such a lathe digging slightly too much into the metal causing chattering ( if you've ever used a lathe and dug in a little too deep, you know ) and the marks were not sufficiently ground and polished off before using the die. Might be why they try dies. Report this Post to the Staff
