How do I determine the difference with Planchet

friend

I really need some help. I want to make coin collecting a big part of my life and I read and I read, but I still don't get it, how long does it take to understand even the minor tech terms of collecting. Ok, getting back to my original question, I see a lot about different planchet on certain coins, how does a Newbie determine the difference between the correct planchet and a different planchet. I'm not even sure if I know what a planchet is, I think it is the base of the coin where the coin begins. If this is wrong PLEASE corret me. Also could someone explain "Clad" sorry about these beginner questions I just feel that a lot is passing through my hands without me even being aware. Thank you.

A planchet is the blank, round piece of metal on which a coin is struck.

"Clad" coins are coins that are stuck on planchets that are a core of copper covered on each side with a layer of nickel.

Solid alloy coins start as bars of metal. the bar is rolled out under pressure to form it into long strips of metal. From this strip of metal round disks of metal are punched out. These disks are called "blanks". (Some people use the terms Blank and Planchet interchangably. This is not really proper but is so commonly done that you will never get them top stop.) Other terms used for these are Type I blanks or type I planchets.

The blanks are then put through the upsetting mill which compresses them, reducing their diameter and giving them a thickened rim. NOW they are planchets. (Also called type II blanks or type II planchets.) Flat piece of metal = blank, piece of metal now ready to be struck into a coin = planchet.

Clad = A metal "sandwich" where a central layer of one type of metal has had two layers of a different metal or alloy bonded to it. Normally the layers are bonded together by rolling them together under high pressure. (This is to keep it from being confused with plating where the outer metal layers are usually bonded to the center by being deposited electrically.)

Wrong planchet = a planchet intended for a different coin was used by mistake. As in a quarter struck on a dime planchet.

Wrong metal = the planchet was made of a metal other than what that coin is normally struck on. For example a cent struck on a dime planchet would be both a wrong planchet and a wrong metal error. The 1943 copper cent or the recently discovered 1983 cent struck on a brass 1982 or earlier planchet are examples of wrong metal, but correct planchets.
