it looks like baking soda and snow. haha i dont know shit about coke, just thought id put my 2 cents in
about 4 bucks. I'll be a champ and give you 10. Seriously though. No one can tell you have much that's worth from looking at a picture. It could be cut to shit, not to mention coke's not as easy to eyeball as buds.
It is deffinetly coke because if you just put a spec of it on your lips it goes completely numb! Also it was being sold at a party were everyone was getting coke from this same dealer.
take another pic with something to judge size in it.. would be much easier to give you a ball park that way..
i would say thats over 2 grams,maybe closer to a eight ball. its really hard to judge with it powder and rock,i always got rock back in the day.. assuming that its not heavily cut i would say its worth at least 100 bucks. to check for purity do a bleach test. fill a shooter class full of bleach, dump in just a bit, cocaine WONT turn orange in bleach, amphetamines, turn red, coke forms a slow milky trail that slowly falls like snow, any inactive filler just sort of clumps white at top or bottom but DOES NOT fall in a milky snowy trail. if its pretty pure in most markets its worth between 100 and 150.
