as far as SS pots I usually get between $1 - $5.00 per pot/pan depending on size, condition, and especially if they have the lids.
most utensils are just nickel plated steel and worth only steel pricing.
The most common types of Stainless out there is 304SS & 316SS
304 is a lesser grade and is not magnetic. Most good cookware and restaurant appliances are this grade. Also some of this is in faucets and is considered "investment cast Stainless" I usually keep it with the 304. Also flexible metal hoses from the natural gas lines of ovens are 304SS.
right now 304SS is about .40 cents per pound. This is low right now. I would hold it if you have the room or don't need the cash right away. When times were good 304SS was over $1.00 per pound
now 316SS is a higher nickel content blend. It also commands a higher price, usually .10 to .20 cents more a pound. Again when times were good this was up to $1.60 per pound. If your yard does not have a separate rate then see if another one does, if it's close and you have enough. Items made with 316SS or 316L are usually stamped with a 316 somewhere one the part. Industrial and instrumentation fittings, valves, flanges, and tubing. Most home used products are not 316$$
for some utensils and plating ... make sure it's not silver!
I don't run into much 17-4SS or the other types. Some times cylinder rods are 17-4ph SS though.
hope this helps. I go through a lot of stainless.
happy hunting
