It’s more dependent on your local market and how good the wood actually looks. Is it knot-free? Have a really nice pattern or grain?
Usually, the wood that you are talking about should be easy enough to inspect without giving too much thought to the pattern or grain, but when talking about wood in general there are lots of things that matter. When you start talking about more exotic pieces, the little things can really start to add up making one 6’ board cost several times more than another of the same species.
Also, do you have a moisture meter? You might want to make sure their wood is dry. I’ve seen some boards that are “kiln-dried” that come out to some pretty high moisture contents… something that is usually a dead giveaway in the price.
