Copper is a soft metal, and scraps easily. If a batch of copper cent blanks where annealed in an annealing furnace, it is not unlikely that they would leave some copper dust within the interior of the annealing furnace. If a batch of quarter blanks where annealed immediately following a batch of Lincoln cent blanks, and if the quarter blanks where left in the furnace for slightly longer than ordinary, the copper dust could adhere to the surface of the quarter blanks, giving them a coppery surface. This is what does happen, occasionally. Sintered-coating planchet errors are recognized by their copper colored surfaces and the permanent look of the copper on the coin&#039;s surfaces.[/QUOTE]</p><p><br /></p>
