CANADIAN ERROR COINS - TWO DOLLAR PLANCHET VARIETIES

TWO DOLLAR PLANCHET VARIETIES

Types that occur due to variations (errors) that occur during the creation
of the planchet (or components of the planchet) .

"Bumpy Edge Twoonies"

Many 2012 "bumpy edge" Two Dollar coins are being reported across Canada.

The 2D images on right demonstrates the relationship between the "bumps" on the rim of the coin and the lettering impressed on the coins rim. The lettering on the side of the newly designed 2012 Two Dollar coin is applied to the planchet (blank disc) prior to the striking of the coin. In all cases, lettering on the edge of  any coin must be done to the planchet prior to striking into a coin. If the side lettering & design was done by the collar during the strike, the coin would be locked into the collar and unable to eject. The "bumps" on some of these new 2012 Two Dollar coins is due to the  distortion of the rim by the edge lettering prior to striking into coins.

Images of planchets intended for Mexico & Euro coins with "bumpy edges" due to metal displaced during lettering of the edge.



2006 Two Dollar
No Core Strike with Core Hole Off Centre

A very rare occurrence to have a bimetallic coin struck without the core in place.
This coin is a multiple error, the centre hole was also cut off centre.

*Estimated value $1,200.00*



RCM Two Piece Planchet Type Core and Ring


  These are a pair of the pieces that comprise the whole planchet of the Two Dollar coin. 

The Ring has a slight "V' shape groove that that runs along the inside edge of the hole.

The Core edge has been upset in a manner not like regular coinage. The metal has been squeezed to an almost outward "V" shape.

Both pieces have been strongly burnished and appeared to be "Oiled".
*Estimated value $150.00 - Set with both pieces.*

2000 Clipped Core Found in Proof-Like Mint Set

This is a very nice coin found in a PL set.

The Mint is very diligent to prevent errors like this from being released.  However, due to the huge volumes involved, errors do get out. This coin remains intact in its original set and may be worth several hundred dollars.

*Estimated value $300.00*

                  

 

2001 "Knowledge" Misaligned Ring Hole on RCM Planchet Type

I have had the opportunity to examine many of the pieces, as they are very common for that year. At first glance you may think it is a very slight misaligned core type of error.

In my opinion, it is the result of the hole of the Ring being slightly misaligned.

It would seem that a large batch of rings were affected this way, as these are very common on the 2000 issue. (About one fourth of the strike may have been affected).
*Estimated value $5.00*

1999 Unannealed Ring

I have had the opportunity to examine coins that do not to exhibit the uniformity of most Two Dollar coins, in the "meeting" of the two separate pieces. In some cases, it appears to be due to a weak strike.

This one appears to be more like the result of an unannealed ring. Annealing is a process of heating metal and letting it cool naturally to soften the metal.
*Estimated value $30.00*

                 

1999 Nunavut - Core with 2 Curved Clips

Small clips can usually fetch $100.00, while a large Clip may get double that.

The coin illustrated here is the first reported Clipped Core on a Nunavut commemorative. It is also the only reported Double Clip - on any Two dollar issue.

*Estimated value $300.00*

Misaligned Ring Hole with a Clip

 

If you look closely at the image, you will note that the core is perfectly round on both sides of the coin. This is unlike most "Misaligned Core Strikes" commonly reported. Misaligned Core strikes show one side with an elliptically shaped core, while the other side will show an oblong shaped core.
To cut a ring from a strip of nickel is a two part operation. First the "hole of the ring" must be punched from the strip. The "Holed" strip is then feed into a guide that aligns the "Ring Holes" to gang punches that cut the rings.
The example shown here shows evidence of the ring being punched out of alignment with the centre hole. The arrows indicate a small curved clip on the outside of the core.
This is the second such example I have been able to examine, the other being dated 1996 -it had a small curved clip on the outside of the Ring also. I estimate the value of the one shown here at around $200.00.

*Estimated value $200.00*
