Hello I came across this it may be weather damaged and currently do not have a scale to see if the weight is different from others but was there any coins minted in 2012/2011 with an inner core very dark as this coin
The inner core composition surely would be affected by Environmental Damage - quote - "Prior to 2012, the coin consisted of an aluminum bronze inner core with a pure nickel outer ring; however in spring 2012 the composition of the inner core switched to aluminum bronze coated with multi-ply plated brass, and the outer ring switched to steel coated with multi-ply plated nickel." closed quote I want to share this wepbpage with you - https://en.wikipedia.org/wiki/Toonie
