Looking at the local FB marketplace I saw this old 34” saw blade for $100. 
 

Assuming it’s good steel, how much would you pay for it?

I would buy known steel from a steel supplier if I had that amount of money. I'm not really sure how much that would be though.

What are the prices for new steel in of known composition and heat treat?

It is worth a lot more to someone who wants to paint a picture on it.

Scrap price for me. 23 cents per lb.

I wouldn't pay more than $5.00 US for it.

Folks,

You can probably buy many new circular saw blades for $100. 

Sorry I.D. F. & C,

Herr  SLAG  bids $5.15 for it.

For $100 you could buy a nice 2" wide monosteel bandsaw blade new and know what you have. Senor Slag clearly outbids me.

As usual questions about 'worth' are subjective. If I was making a sculpture and the final missing piece was a large circular saw, perhaps I would pay a higher than scrap price. 

So it is all about how much it is worth for me ... or rather for you. For the others it obviously is overpriced because they are hinking in steel value. Bieing it most likely comes from an old mill, it can have value for different reasons that are not it's steel content. 

They do very well for target practice because you can hear when you hit it

In the interest of better Missouri - Alaska  friendly relations SLAG,  Industries L.L.C. will be most pleased to gift said circular saw blade to representative  Hon. J. Frosty of the exalted state of Alaska.

Respectfully submitted,

Herr SLAG.

I like the way the shadow looks like it's checking a tooth for sharpness.

That's quite an old school blade, not having the usual semicircular inserts for replaceable cutting teeth.  I wouldn't use it for blades as it's value is really in being an "antique" decorator piece..or painted as someone mentioned.  The price reflects that use and it would go for pretty close to that around here plus or minus.

Much better value to buy known steel in a shape and size that's appropriate for the work and use that...or, if one really wants to "recycle",  buy good scrap of a similar nature that doesn't have the premium cost adder of being a semi-antique.  Your local pawn shop probably has a bunch of smaller blades at something like a buck or two each and you could harvest far more steel for the buck.

 

I have one or two laying around here, Humm............

Any local sawmills?  They often have a pile of old blades around.  Doughnuts make a good winter conversation starter.
