Pennies glued to a cardboard collar, to deter both slugs and weeds.

This is an awesome idea but you want to use pennies made in 1981 and older. Those pennies are 95% copper. Pennies made after 1981 are only 2.5% copper and 95.5% zinc.

Even though they are only 2.5% copper, it is a pure copper plating around a zinc core. So any slug crawling across a modern penny is still coming in contact with pure copper and it will have the same affect as an older copper coin.

I didn't take the time to sort out the vintage of pennies -- just slapped them on willy-nilly. It was a very quick project - glue, slap, glue, slap. A child would enjoy this one.
I want to live in a world where the chicken can cross the road without its motives being questioned.

Has anyone tested this by putting a slug in the middle and seeing it if makes its way out?
