bosox Pillar of the Community United States 1352 Posts	Posted 02/28/2013 8:45 pm These coins probably were struck on different coin presses. I am guessing that all of the collars were not all perfectly 25.4 mm. and the planchet expanded into a slightly larger collar upon striking. http://www.victoriancent.com 2011 & 2025 Fred Bowman Award Winner, 2020 J.

darutis New Member United States 9 Posts	Posted 03/01/2013 9:07 pm SPP-Ottawa you have analyzed the Bank of Canada's National Currency Collection 1859 brass cent. It is less than 90% copper, more than 10% zinc and contains no tin. Tell me, what was the weight of the coin and diameter? Report this Post to the Staff
Bill in Burl Valued Member 197 Posts	Posted 03/03/2013 3:17 pm Darutis ... I finally found my caliper and thought that I would give you the diameters of 10 random 1859 bronze cents. I have at least 600 in albums and another 300 or so loose to look at some more. Here is what I found in a completely random stack of 10: the 10 ranged from a low of 26.67mm (1) to 27.94mm (2) with most in the centered (within .05 mm) at 27.56mm. As Bosox said, the planchets were ordered at 25.4 mm and the collars for the dies had to be a little bigger. When the when the hammer die met the anvil die, then planchet had to expand due to the pressure; hence the larger diameter than the 25.4 start. Report this Post to the Staff
