1870 Narrow ‘O’ Canadian dime

1870 Canadian Dime, we have three coins.
The initial design for the Victoria 10 cent pieces issues by the Dominion Government were identical to those of the 1858.
Two styles of ‘O’ appear in the 1870 issue. The narrow O with sides of equal thickness is more common then the Wide O, on which the right hand side is thicker.
