What are Eames 'Time-Life' chairs worth?  

At the risk of sounding snippy:
as a seller, you should already recognize that the "worth" of something is highly subjective and dependent upon who's selling it... where they're selling it... even when they're selling it.
Offhand, I think it's safe to assume that fabric-upholstered versions of this chair would sell for less than the leather.

You might do better offering them individually--
the pool of buyers shopping for a set of ten office chairs has got to be tiny, compared to those shopping for one.
(Also-- I hope you're using a reserve? Starting ten chairs at a penny seems risky, a low starting price should be used only if you're confident that there's a big audience for your item-- how many people are shopping for TEN chairs?)

Don't worry
He will end the auction early if it doesn't reach desired price.

Considering that most
buyers 'snipe' during the last few moments, that seems a foolish, inefficient way of selling on Ebay. (ending the game before the action really begins.)

eeghh
Unfortunately the Time-Life chairs aren't the most desirable of the Eames. Interesting historically, but not really timeless in the manner of the Alu group. I would say the fabric factor also brings that down further. Lots of folk will avoid fabric as being icky/dirty/whatever. Set a decent reserve on one and see what happens. Echoing the sentiments that a set of 10 is a big gamble - the chair is uber specific, you either love it or you hate it.

Gee...
it seems there was "an error in the minimum bid or reserve amount." Too bad for those who wanted to bid.

I have to say
The red is a little better than I expected. I was thinknig one of those horrible corporate beige tones. Still very specific.

Update: the 10 are going to a well-known LA based store that will fully restore and cover them in some very interesting materials.
also, I've been sitting in one at my computer for the last week and it is by far the most comfortable mid century chair that I've ever owned (that says a lot!)
