1919 Canada Half Dollar Grade?

EF45
Nice coin

The coin has issues,for sure,that's why I didn't give a value,but grading of Canadian circulated coins is strictly a function of wear,market grading isn't fully accepted here yet.

According to Charlton;
VF20...the central bands,jewels and pearls are worn away.
EF40...the bands and jewels of the crown have lost their round contours. they are flattened.

this coin is easily EF40 with a value of $150.00

I would agree with neweden Standard Grading Guide - James Charlton & Robert Willey. VF20 The eyebrow is considerably worn. The band of the crown, its jewels and the shoulder bow are clear but not sharp - EF40 The eyebrow is worn and there is slight wear along the band of the crown. Other details remain clear and sharp.
From this I would say VF30

My concern with it being EF40 would be that the vertical beads in the obverse crown are worn and not sharp, also the jewels in the crown band are quite worn not slight wear. With this said it is better than VF20. That is why IMHO I would grade it VF30. That is just my opinion and not saying that is right.
