I have picture some 26 pieces of furniture including 9 Eames "chip" chairs (2 lounge and 7 side chairs), 6 Aalto dining chairs, 4 Saarinen grasshopper chairs, 1 Eames coffee table, 1 Eames folding table, 1 Noguchi "spoke" table, 4 Bertoia side chairs, and 1 Aalto round dining. All are from the 40s and 50s except the round Aalto, a recent Artek item. Condition is, as you will see, not great. I am interested in selling all or some and am already getting some offers, but am a little unsure what prices these items should bring.
Some nice stuff there although as you said condition isn't great. And that is definitely one determinant of value.
If you sell to a dealer which may be the easiest and fastest way to get money for your items in a short period of time, expect them to decide what they can sell it for and then they probably would want to pay you about half of that value if in a condition that is saleable. With many of these items they will have to have reupholstered, refinished, repaired so expect the offer to be much less than half.
Say for instance that a Grasshopper chair would sell for $2400. Generally, they would want to only have about $1200 into the chair to make it worthwhile to sell it. Well they probably are looking at $500-600 (or more) in upholstery and refinishing so they may only want to pay $700 or so for chairs in this condition. Now if it was a surefire quick sell for them or a very desirable item they may be willing to pay more but you get the idea.
As far as retail (mid-century shop) prices in restored condition I would guess $2000-2400 each on the Grasshopper Chairs, around $100 each on the Bertoia side chairs, $2000 on the Noguchi table, $1500-1800 on the Eames Dining Table, $200-300 each on the DCM's, which can vary widely in value based on version/wood finish/etc, but many are screwed through which decreases the value alot on those. Just a start but there you go an a few pieces...maybe others have other ideas or values on the other items listed.
Also, keep in mind that specific labels, specially on the Eames items, could make them more valuable.
