Someone New Member United States 3 Posts	Posted 07/02/2006 02:14 am Hello. I found a blank coin on the ground next to a post office. It is the size (almost exactly, I think) of a U.S. quarter. The edges are neither raised nor milled. I thought it was a U.S. quarter planchet, but it appeared to be ferromagnetic, unlike the U.S. quarter. I read somewhere that a coin could lose its magnetism during compression, however the U.S. quarter is only 8.33% nickel, whereas a nickel-copper alloy needs to be at least 56% nickel to be ferromagnetic. I found two coins in my possession of almost the same size (and color) that were magnetic: a Canadian quarter (1982) and a French one-franc coin (1978). The Canadian quarter seems slightly too narrow, while it would seem more improbable to find a planchet of a franc on the ground next to a post office in the United States.

Thanks. Edited by Someone 07/02/2006 02:17 am Report this Post to the Staff

FYI Valued Member United States 177 Posts	Posted 07/02/2006 1:35 pm the edges of blank planchets are usually raised on one side and no the other from when they puched it out, or rounded by milling by the mint, or raised from being readyed for minting, but they are never square like that.

Metalman Pillar of the Community United States 7123 Posts	Posted 07/02/2006 1:48 pm actually blank planchets come both ways, they can be flat or having been through the upset they can have rims. but they will be materially correct, meaning clad layers and core in the US ,, Rick Report this Post to the Staff
