Hi Nohope
This is a nice example of this date, if you want to take a look in my gallery, I have a pic of the same date in a known uncirculated, the pics are a little small ( I still need to retake them)
but the details are fairly visable.
your coin in my opinion grades EF-45 based on a couple of things, the wing tips, the beak and the ribbon on the reverse,the leaves and outline of the 50 and the cap and upper ray ends all of these elements show some wear.
