Checking ebay, undamaged circulated examples seem to go for a dollar or two. I would think a damaged one would be substantially less.
The Dent is just damage. The missing initials is caused by an over-polished die. The evidence is the slight floating roof which is common on Cents minted in the late 1960's IMHO.. Worth? 1 Cent
I did see a few on ebay selling for 3-4+ but they didn't have the ding on it like your coin has. If you fancy it, keep it for your collection, if not, wrap it up!
