The technical name for a coin blank is "planchet" or "flan".
In common use, the word planchet generally is used for a coin blank that's been punched from a flat sheet of metal but has had no other changes. After that the blank usually goes through one or more preparatory steps before the design is added. Blanks are put into an "upsetting machine" that squeezes the circumference very slightly to produce the raised edge you see on the rim. These partially-processed blanks are more frequently called flans, although to again be technically correct a blank without a raised edge is also referred to as a Type I flan while one with the edge is Type II.
Once the raised edge has been added the coin blank is fed into the press that strikes the front and back designs into the metal and, if appropriate, adds reeding or other tactile features to the edge. Once it receives its images the planchet has become a coin.
The metal disc used to make a coin is called a "coin blank" or, more formally, a "planchet." They also used to be called "flans," but that term is no longer as widely used.
You have a blank "Planchet", a metal disc prepared for the minting of a specific coin. Apart from the novelty of having one, they are not rare, the Royal Mint has tens of millions of them, and they are not worth anything.
Very little ! With no identifying markings at all - it's essentially just a small metal disc !
The term "struck", when referring to coins, means the making of the coin. The blank planchet (the round blank disc which will become the coin) is struck (pressed) between the dies and the coin is made.
It depends, sometimes they are called blanks, other times they are called planchets, occasionally you will hear them called flans. All of them are correct though the term planchet or flan is used more with coin collectors while the term blank is used by pretty much everyone else.

Diamond mini cutting disks sound like a cutting tool for a Dremel or a similar small machine. It's a metal disc about the size of a coin but thinner that has tiny, tiny industrial Diamonds embedded in it. They cut metal and glass just fine.
no. in order to burn info on the disc the computer has to recognize it as a blank disc. once any in has been put on it it will not be recognized as blank even if the disc has more space. trust me. I've tried.
we can write the blank compact disc.
