"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.

Update 2016 - Bumpy edge Twoonies continue to appear in circulation.

It is obvious that the mint here is not concerned with these coins. It must be due to the slow evolvement of the upsetting of the planchet to create the rim on the final coin, to preserve dies. In the past, prior to upsetting planchets - dies form the rim entirely and dies wore out quickly. Modern dies have have the edge grooved and are not so involved in the creation of the rim as in the past. 
The bumpy edge planchets are not damaging dies as may be perceived.

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*

Two Dollar Multiple Error

2011 Two Dollar
20% Off Centre with a Straight Edge Clip

This coin was received as a gratuity by a hairstylist in Calgary, Alberta. 
*Estimated value $1,200.00

A very rare occurrence to have either an off centre or a straight clip on any coin. This 2 Dollar coin has two separate types of errors and regarded as a multiple error. The Straight Edge Clip in this case is an error made in the creation of the ring. The ring appears to be punched from a cut end of the strip of metal rings are punched from. Then it was struck as a coin, off centre to the dies and collar.

It is possible that the orientation of the "clip" at 12 o'clock position, along with the off centre strike, caused this coin to be struck in a condition more likely to pass inspection. It is rounder than if it was struck in the collar with this size of clip. Without this size of a clip at that position and as an off centre alone, it would have been a more readily screened. Coins in Canada have traditional had the planchet pushed in to collar from the 12 o'clock position. In my opinion, this is why it was pushed short of the collar.
