Let's discuss buffalo nickel grading
When I was younger, a full horn, full date was needed for a VF. A fine generally had a partial horn and sometimes a partial or very flat/worn date. I remember buying buffalo nickels out of a bucket and the dealer would look at the date, the braid, Liberty and the horn. Anything with a full horn, full date was a VF at a minimum unless it had major problems. To get to XF, everything had to be sharp with only light wear on the high points. A VF never had a partial horn, that was always a fine or lower no matter how nice the rest of the coin was.
So is this the standard today or is a partial horn acceptable for a VF coin?
Here is an example from eBay (not mine) where the seller calls this 1927 a VF+ partial horn.
