Cascade Pillar of the Community United States 7390 Posts	Posted 03/11/2016 12:25 pm What do you think? I've never seen.an ex encased with markings like this. Was the notching to hold the coin in more securely? Or do you think it's from something other than an encasement? Report this Post to the Staff

moxking Rest in Peace United States 17900 Posts	Posted 03/11/2016 12:59 pm Nickel isn't soft. It would have taken some serious pressure to create that edge around the periphery. Although I can't think of a single way that one edge (on the obverse) would have a cloth pattern, and the other side (reverse) almost look like it has reeding from any mint process. That's a head scratcher. Hopefully our Emeritus Coop will arrive to enlighten us. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 03/11/2016 1:08 pm Probably to help it slide into the collar it was to be added to. Cents are soft. Nickels are harder because of the 25% nickel. so they probably figured out that had to be able to make it fit better without cracking the encasement. (first time I've seen a nickel used before) Added to my educational files. Thanks for posting this. Report this Post to the Staff
Pete2226 Pillar of the Community United States 3330 Posts	Posted 03/11/2016 1:32 pm Quote: Cents are soft. Nickels are harder because of the 25% nickel. This is not correct. Cents are slightly harder than Nickels. Cents are composed of Zinc ALLOY 190: COMPOSITION (% by Weight) Lead = 0.005 max; Iron = 0.010 max; Cadmium = 0.005 max; Copper = 0.7 to 0.9; Zinc = Balance. This Copper Plated Alloy has a Rockwell Hardness (72T Scale) of 62-72. Nickel is "Monolithic Cupronickel" 75% Cu, 25% Ni. This has a post anneal hardness of 60-69. So the Cent is *very slightly* harder than the Nickel.

Pete2226 Pillar of the Community United States 3330 Posts	Posted 03/11/2016 1:36 pm I should add that pre anneal Hardness for Cupronickel is 88. It is harder than cents before it is annealed. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 03/11/2016 2:31 pm I was looking up some information on this subject and didn't find what I wanted to, but found something I didn't know: It show the life of cent dies a little higher than I had thought. (estimation of 1,000,000 per die) But the other coins dies were a lot less than I a thought. (200,000 averaging per set of dies) This is from the Cherry Pickers Guide. Report this Post to the Staff
Cascade Pillar of the Community United States 7390 Posts	Posted 03/11/2016 2:38 pm I figured it had to be encased. Pushed metal and all. Plus the incuse rim edge. It's the pattern that had me scratchin my head. This belongs to my lcs owner buddy that consults with me on vams toners and errors as they're not his thing. He thought it was struck on a foreign planchet but I told him it was not a mint error and probably an ex Encased Coin. Thought I'd get a consensus here though as to encased or not so I can give him a definate answer as to what caused it if possible. Glad I (or actually he) could help with your edu files coop lol Weight is spot on at 5g still and diameter is relatively unchanged. Oops, forgot to add pics of the edge. And here's better pics out of the 2x2 for ya coop... Report this Post to the Staff
