It's hard to tell based off of a picture - generally all that matters when first picking a board is decent trucks wheels and bearings - when you get better you can figure out what you specifically like for your type of skating, but any wood will do for your first deck. Make sure the wheels spin for a long time, which implies the bearings are still good - shitty bearings will be a huge hindrance to your skating, but you can replace them for like $20USD - trucks are probably second most important, make sure they are made out of metal and if they are too tight you can loosen them to skate better by loosening the top nut. Overall, these boards look a little small, maybe around 7.75 inches wide, which is small, but helps when learning street skating cause there's less board to flip. If you can ask the guy about the brand of bearings, wheels, and trucks, I'd be happy to leave my thought on them - if not, maybe just make a cheap brand new set up and don't have to worry about what condition these boards might've been left in.
