CANADIAN ERROR COINS - GERMAN PREFAB TYPE PLANCHET VARIETIES
German Prefab Type Varieties
Types that occur due to variations (errors) that occur during the creation of
the Planchet
or the Striking of
coinage, concerning the German Prefab Type Planchet.
This
is a German prefab Two dollar planchet, which was used before the present method
of a separate core and ring being fed to the dies. What is interesting here is
that neither the core, or the inner ring were upset prior to its assembly. These
types of planchets would probably be more stressful to dies and they would cause
the dies to deteriorate faster. If you note on any Two dollar coin there is a
raised border around the core. On the prefab planchets the dies had to form that
border with out the assistance of the upset type core and ring.
It is interesting to note that all Two dollar blanks examined, have been Burnished.
Burnishing is a process that involves tumbling the planchets in a large drum with small metal pellets. This roughens or dimples the entire surface of the planchet and is helpful in producing the Frosted Cameo-like appearance of the Polar Bear on the struck coin.
Burnished planchets also "slide around" easier and are less likely to get stuck or stick together and cause other problems, like striking errors...
Having the opportunity to examine many of the German made
planchets and the two piece Core and Ring sets produced by the Royal Canadian
Mint (RCM), there are remarkable differences in the Burnishing.
The pieces made by the RCM have a much more pronounced and deeper Burnishing.
The RCM Pieces also appear to be very finely "oiled."
Simply put, the German Type Planchet does not have anywhere
near the "shine" to those by the RCM does.
They appear "Dry" as they do not appear to be finely
"oiled."
We hope to have more information soon regarding oiled planchets.
Quite few German made blanks have appeared, but that supply will dry out as the prefab
type of
planchet was phased out in the early part of 1996.
In time it could be a key piece in
completing a set of Planchets. *Estimated
value $150.00*
The Images to the right are of a Two dollar coin with a Curved Clip on the core.
Generally speaking clips are scarce on modern Canadian coins.
This was the 1st
known on a Two dollar coin core. This error appeared at the 1997 Fall Torex Show
in Toronto and is now in a private collection.
*Estimated
value $300.00*
To look at this coin, you could expect to
see a curved clip on the outside of the ring.
Based on observations of other similar coins.
It may be assume, at this time, that it is on a German
made prefab type of planchet. These are fabricated in a different manner than
the "Rings" Canada produces.
We are still gathering information on this error type.
*Estimated value $200.00*
It appears that the hole portion of the core was punched out twice. Once on
centre and once way off.
It is currently believed to be on a German prefab type.
If it were on the two piece
set currently used, it would
also exhibit a curved clip on the outside of the
ring.
We are still gathering information on this error type.
*Estimated value $300.00*
A genuine Off Centre Two Dollar coin. The arrow indicated an area that was
Struck Thru Grease.
There was clear evidence on the unstruck portion to identify it as struck on a
German Prefab Planchet.
The German Prefab Planchet are burnished differently than their Canadian
counterparts. *Estimated value $500.00*
