It is really hard to convey in photos. Turning the coin so as to look at the entire edge it really looks the the coin was supposed to be reeded. Somebody could use some sort of machine to do it post-mint, but I would think the coin would show other damage from the effort. I say "supposed to be reeded" because it is very faint. Doesn't look at all like the edge of, say, a newly-struck dime. Kind of looks like the edge of some dimes that have been in circulation for 40 years or so.
