Placid

Formed into a mass by heat and pressure.

Sequitur

Maybe not in laymens' terms, but:

Sintered: These planchets were kept too long in the annealing drum. While in the drum, they became coated with a layer of metal dust which the heat then sintered onto the planchet. These are known with partial, single-sided, and double-sided sintering. See also Copper Wash.

Copper Wash: These planchets receive a thin chemical coating usually of copper color while going through the wash cycle prior to striking. See also Sintered.

Many other planchet errors can occur. Cents coined since 1982 are sometimes lacking their brass plating, and dimes, quarters and halves made since 1965 are occasionally struck on planchets that are missing one or both outer claddings. Conversely, they may be struck on just a clad layer that is not bonded to the copper core. Lesser planchet errors include laminated and sintered planchets, but such coins bring only minor premiums among error collectors.
