 Recent error coins found in circulation in Canada-

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.
