One, they don't match. Two, they look to have been reupholstered. There should be furniture tags or marks underneath. Were you looking for to sell them more than what you paid?
Some folks watch the Antiques Roadshow and think they can score big bucks with hidden treasures. However, those items are really rare and just because they say it goes for XXX at auction, does not mean anyone actually pays that.
And like Zin said about spending the time and effort to get them appraised also means you have to pay for appraisals too. So you'd have to factor in the cost of that along with what you paid.
Nope, I think you made a very good sale.
