How many toonies In a gallon?
thats not a valid question a toonie is money and a gallon is a unit of measure
Each toonie is 1.8mm thick. There are 25 toonies per roll so that's 1.8mm x 25 = 4.5cm long. Converted to inches that's 1.77 inches, just shy of 2 inches. This doesn't take into account the paper folded at each end to hold the toonies in. So likely, if rolled correctly, the toonies would be about 2".
