Or in small quantities it was ridiculous prices back over on the west coast. Most common were $25, $30 or $50. ($19,$23,$38 in the US)
People you didn't know in open house 'stick shops' sold foils usually around 0.6-0.8g, sometimes not even dry for $25. They could sell an ounce for between 850 & nearly 1200 by selling in such small amounts
From mates or more reputable dealers $25 got you 1g, $30 1.2g and $50 for 2.5g.
