Some people sell in "nickels" and "dimes." There's a lot of variation on those measurements.

Where I'm from, a dime bag is $10. Aka, a gram of cheap stuff that probably has seeds and stems in it. A nickel bag would be $5, enough to get high once.

Some peoples' areas have dime bags as 10 grams, not 10 dollars. That's a whole 'nother ballpark.
