1964 Canadian Fifty Cent Coin

MS66DMPL

Not my series, but nice coin.

Doubled strike...Maybe referring to a proof coin?

This is the "variety/Error" forum. Is there supposed to be doubling somewhere on your coin or is it an example of a very high grade coin?

I think that the right side appearance is just the lighting/glare coming in from that side. On ANY coin, all the elements of the design are slightly wider at the base of the element, regardless whether it's the monarch or the lettering or the date, etc. That's because the working die is constructed/made that way(on a slight taper) so that the coins don't stick to the die when they are struck. That taper is what makes well worn coins appear to be in a wider font than newly struck ones.

On the working die, the definitive edge of the flat part of the die and the beginning of the recessed element takes the full brunt of the tons of pressure that the presses deliver. That edge wears much faster than the rest of the die because it's just a very thin surface area. It's that edge wearing (and not always evenly) that causes the appearance of " Die Deterioration Doubling" which many people infer that it's some type of repunched doubling or some other type of doubling. Just think of the edge of a kitchen knife, which is about what the very edge of the working die design pattern would be. Then start pounding it with tons and tons of pressure multiple times per second and see how long that edge stays perfect. That's what causes apparent "doubling" on some coins, when all it is is just honest wear on the working die.... or an example of " Die Deterioration Doubling". To counteract some of this edge chipping/wearing away, some dies may have a very slightly beveled edge to spread out the tremendous forces of the presses. This gives some coins the appearance of also being slightly doubled at the very vase of the design elements of the coin, against the flat surface of the field.

Thanks for the info Bill
