Wegner Folding Chair with Damaged Hand Holds  

A lot.  
 
To repair that break, the handle needs to be broken off completely and then glued and clamped.  This would require re-caning.  

Thanks Leif.

As Leif said, the value will likely be affected quite a bit.
If I were approaching the repair of that break, my first course of action would be to put a clamp on it and see how well it clamps together.  If it clamps really well, and closes completely, that indicates that there is no debris inside (misaligned wood splinters, grit, glue from prior repair attempts, etc.). 
My next course of action would be to see how far I could comfortably open the joint to expose the inside of the crack, to better glue it up.  I would likely not try to insert glue directly into the crack if I could not really be certain that I was getting good coverage on all the surfaces.  If I was certain I could completely glue up all the surfaces, I would do so using Titebond III, then clamp it up.  In your case, I am not sure that crack could be wedged open very much...
Although, I might add that you can get quite a lot of glue into a rather tight spot using a lot of glue and an air compressor to blow it into the crack.  It can be a messy operation though.
If I could not open the crack enough to glue it up properly, I would then use a 1/16 inch drill bit, and drill up from the bottom side of the stretcher, up to the cracked area.  I would then use my high pressure glue syringe (not one of the cheap glue syringes you buy at a hardware store), and using the 1/32 inch brass syringe tip, I would send glue into the hole until it flooded out all around the edges of the crack, then I would clamp it up.  I have done this method many times, and it has so far worked very well.
It is very easy to break a 1/16" drill bit while drilling, especially drilling a hole that deep into a hardwood.  You have to back the bit out frequently to clear chips, try not to get it hot at a high rpm, and hold the drill steady to not stress the bit.

Hand holds are damaged in this folding chair as it is quite clear from the pictures and needs a repair with the help of glue/ bonded or some sort of adhesive of color matching to the wood. Also some sort of  very fine filler material is required to fill the fine cracks with very strong adhesive and then follow the process of sanding and polsidhing the effected parts only of the chair before going to complete polishing to give a synchronized look.

Thank you, all of you are clearly very knowledgeable and your respnses beg a couple more questions, thanks for bearing with me.
How would I find someone qualified to make this tye of repair?  I tinker with "junk" furniture", but I do not have the equipment or expertise for this one. So far I found several who repair the cane or rope, one make "minor" carpentry repairs.
Approximately what would this type of repair cost?
Is it more saleable with or without the repairs?
With this type of damage is it worth having it appraised, or just list it for auction and see what happens? I have under $200 invested at this point.
Again any info you have and want to share is much appreciated.
 

If I were keeping it, I would attempt a repair similar to tchp's recommendation above. If you are not comfortable with the repair techniques and are primarily looking to sell, I would leave it as is. The worst thing you can do it pay someone without experience in this type of work to attempt a repair and end up with a poor irreversable repair. 
 
Your current investment amount is very good and you shouldn't have much trouble making a decent profit selling as is. The vast majority of these folding chair designs out there are the vintage Yugo knockoffs, and some of those end up selling for what you paid for your Johannes Hansen.

I agree with cdsilva. A poorly done repair would be much worse than the current condition, which done right could be a perfect repair (ie invisible and strong as new).  

cdsilva has it exactly right.
Sage advice there.

One wonders what caused those breaks -- in both handles ?
What is causing the chair to "open and close a bit rough" ?  That needs exploration; are the pivots damaged or worn ?  Is something interfering with the action, elsewhere ?  Whatever is wrong needs to be addressed before it gets worse.
Considering the condition of this chair, if the owner were going to keep it and simply put it to use, I'd be tempted to call it a "beater," put a screw or two into each of the handles, from below, and call it a day.
The correct and complete restoration calls for removal of cane, repair of frame where needed, and re-caning.

How on earth can you call that a beater? If it was a Yugo, then yes, a couple of screws from below would be fine.
 
As tchp already noted, if there is some flex in the cracks, then it looks to be a very reasonable shot at injecting glue and clamping. I would even consider the Gorilla Glue if it was teak, as it is an oily wood and acetoning the surfaces is not an option inside the crack. It is also a glue repair that it is not being used on a joint that may want to be disassembled in the future. I did this same procedure on a similar crack in a Erik Christensen boomerang dining chair a couple of years ago and it has held up very well.

Your current investment amount is very good and you shouldn't have much trouble making a decent profit selling as is.

I listed this on ebay today as a 10 Day auction and will let you all know what happens. I (and especially my 30 something kids) wish we could keep it), but that's not the objective here 🙂 (which is to get them, and my first Grandson home for the Holidays)-- I sincerely appreciate all of your knowledge and especially ~ willigness to share your amazing expertise--I too will share what I can going forward.

Final bid of $2490; pretty good eBay price. Should be a good holiday.

I had high hopes of being able to bid on this, but it was clear after a few days that it was going higher than I was able to go.
