@mngrif The American $1 note was a popular one for cyclists -- some carried one on the tool kit when riding. The tough paper it was made of made it a good way to patch a cut tire, as long as it was not a catastrophic failure. Fold it up a bit, mount the tire with the bill inside on the ripped area, inflate and ride.

Our canadian bills are not made from that new strong polymer, Australian invention, never tried but it might be good for the same job.

Sadly, that would cost you $5 CAD, the smallest bill we have nowadays.

We got the Loonie $1, the Twoonie $2, then $5 polymer bill.

I really, really love the older, silver coinage. That is REAL money -- worth it's weigh in Troy Ounces, 90% silver on US pre 1965 coinage.

Even the sound those coins make, jingling in your pocket, is a delight. Crystalline!
