SirMike1983 

There are many different chrome steel rims worth saving. A good set of Rigida or Araya rims are worth saving, as are a good set of Schwinn or Raleigh rims. The old Dunlops are also worth saving in condition. Then there are the unusual old ones like the pre-war Lobdell rims. With Schwinn rims, extra care should be taken to differentiate a chrome steel rim and a stainless rim. The same is true of 1950s Raleigh rims with matte center - set those aside as unusually good rims.

I would not throw any away if they are in good condition. I'd keep the better-made ones and donate the cheapos to a bike co-op, charity or bike shop. The only ones I would recycle bin/trash bin are cheap, no-name rims in bad shape.
