World Blank Planchet
World Blank Planchet

In modern minting technology, a planchet is a coin blank that is fed into a machine where it receives the coin pattern when struck at high pressure between two coin dies. Usually blank planchets are upset prior to striking. That is, they receive rims before entering the striking machine. The blank planchet in our picture is for a US Lincoln cent.

Daniel has a blank planchet for a Canadian Loon dollar, found at this link on CoinQuest. You rarely hear them called 'loon dollars' in preference to the endearing 'loonie.'

The problem with blank planchets is that one is not often sure where they come from. In Daniel's case, it is a blank loonie for sure. But proving that may be difficult. A genuine loonie weighs exactly 7 grams, and this helps in identification.

Most blank planchets run between $2 and $10 US dollars retail when they are unidentified. When completely authenticated and identified by a major numismatic service, such as PCGS, NGC, ICG, or ANACS, blank planchets can tip the scales at $200 or more.

If I had a blank planchet from a bi-metallic coin e.g. Canada $2, Italy 500 lire, would it be both metals, or just one?
With these types of bimetallic coins, they are designed so that when the center is placed inside the outer ring and then pressed, the two parts are bound together and can withstand a great deal of force without coming apart. It would be theoretically possible to have one or both parts separate and un-struck (blank), but typically this would be much easier to notice before they could make it out of the mint and into a collection. As a rule, because these coins need to be pressed/struck to create the bond between the two parts, it is unusual to have a blank planchet of this type - but it is possible. - CoinQuest (Todd)
