In the states, 1943 pennies were not made of copper (except rarely) because copper was needed in the war effort. The first effect I got based on the properties of this coin was more than 40 years ago. It was a clever paddle trick (maybe some of you old timers remember this!)
Since then, many more effects have been developed using these coins. Because of this, and their popularity with coin collectors, the end result is that they have become somewhat scarce.
Nonetheless, a quick search on Ebay will find you as many of these as you would like!
Now if you can live with any other coin aside from a penny, there are many gaffed coins of this type available on the market. Quarters and fifty cent pieces are fairly easy to come by. They can be a bit pricey, but for the strength of an effect are terribly worthwhile.
