yeah, i doubt thats more than 2 grams. that was in a small bag, and that coin didnt look like its much bigger than a US nickle. the best way to measure out grams, is bowl packs. my bubbler can pack roughly about .7 if i pack it fat. but, usually id say i smoke about .25 to 1/3 a gram per bowl. depending on density, quality, etc. a normal bowl is prob about 1/4 a gram, just if i had to scale it. but each varies. but just think of it this way. if it looks like you can get about 3-5 bowls out of the bag, it's probably a gram or so.
