Saarinen knock-off from Metalcraft Products (60s) ??

I'm guessing about $2. Whether it's vintage or not, it's still a knock off. Good luck.

That's not really fair.
It may be true that Missy's set is worth no more than a similarly-sized, similar condition set that ISN'T styled like Saarinen's, but it's inaccurate to say that the value of a set like that is only $2. Used dining sets -- even ugly old characterless nailed-together pine dining sets -- generally sell for more than that.
I have no idea what this particular set actually sells for, but I've seen it advertised for around $500.

Not it's real value but...
Not that this is it's real value but I did some research on the small side tables. People sell knock offs for about $200-$300. I've seen the original knoll side table selling for about $500-$800. And that's just a small one.
But prices are very subjective. Those are most likely store prices or ridiculous ebay prices. You wouldn't be able to sell a knock off for that much on your own.
I'd say your's could be around $200. But I can see why it's worth $2 to some of those purist.

Prices
Well I have a cute vintage knockoff set that I bought for $99 on Craigslist. I think I got a good deal even though my set is in crappy shape and needs a tonne of refinishing.
Like many people, I'd never be able to afford the real thing, so I like a vintage knockoff. I don't think there's anything wrong with that.
What I do think is wrong are the current knockoffs that are so cheap and flimsy and scream that they're cheap copies.
Anyhow, back to price - look around and see what people in your area would pay for a knockoff vintage set. I know here I could get about $500 once my set is in decent shape.
