Listed at $100 but I have never dealt with a dent before and I'm unsure what to make of it. I am having a hard time dating the frame, any guesses? Any advice on dents/dings like this on an otherwise relatively clean frame?

As for date I would say mid 90's based on no lugs or shifter braze-ons and slightly OS steel tubing. should be a OK buy at $100 if you can look at it in person and the dent isn't too bad meaning dented but not crimped or cracked it looks a bit on the edge hard to be sure from just pics. If actually just dented should be fine to ride and pretty good buy.

Can you give an example of "crimped or cracked" just so I'm clear what I'm looking for?

Pretty frame. I always get nervous when people clamp their bikes by the top tube. If they have previously clamped a skinny tubed frame and then go onto clamping something oversized and forget to adjust, they run the very real risk of crimping their frame. I always clamp by the seatpost and even then, my stand's clamp is the type where you have a sliding jaw that you manually have to adjust and then fine-tune with a knob. But even with that, I wouldn't clamp the top tube.

Edit: Just wanted to say, that I did not mean to imply that the clamping of the top tube caused that dent.

One simple way to check degree of dent is to look at in person putting a metal strait edge ruler on all four sides too see just how big it is. If a frame is cracked you will likely see it and if crimped the strait edge will likely not lay flat to the tube on one or more of the sides.

Dent frame may be warped. Check alignment in person or no go.

That ding looks rather minor, rolling wood blocks could take that down and may or may not burnish the paint. I drilled and cut some out of hardwoods one can use them a few times cleanly. I’ve used faceplate stems of correct diameter, clamped and did not roll. Rolling probably would do more but will bork the paint.

This was not performed on heat treated steel. I doubt the action that caused the ding affected the alignment. If you take a look at it bring a strait edge to check for bowing. Look at the headtube and seatubes together inline. Look at the bottom bracket and top tube centered on bb, glance at front hub wheel forwards, the front hub should be in center of top tube. Both of those looks are for twisting.

My guess on frame age is 1996

^^^^^^ IMO, Not much to be concerned about.

I could be worng, but I beleive that *Paul Brody on youtube has a vid on rolling out the dent with blocks. If not, plenty of other 'net posts about how to.
Of course there's the repaint afterwards...
