It looks brown and shwaggy, I would not pay more than $100 for an ounce. The second pic with the flash makes it look a lil greener
any tips on quickly knowing some key factors just by looking at the bud?, how could it be laced, etc..
It's 99.9% likely that it is not laced. Looks like low-mid quality but that's about it. I agree with coty, would not pay above 100-150$ per oz depending on what weed is like in your area.
It could be laced with fairy shit. The only way to be sure is to bust out the black light and look for tiny footprints.
