" I'm thinking about joining the club since trump announced ending the penny, " I'd say it is pretty late to join the club. Yes, of course you CAN, but the returns have dropped over the years. In 2007, I was running about 16% copper in my boxes. I also was getting about a dozen wheats or more. By 2012, I was down to 8% coppers and 5 wheats per box. By 2019, I was down to less than 5% coppers and 2 wheats on average. So I stopped at that time.
Overall, I have over 14,000 wheats, 375,000 coppers and 9 Indian head pennies. But the ratios are now so low that I don't do it any more. So do what you want, but know it is now a lot of work for a little return.
Oh, and the reason? the BILLIONS of new coins that are put out each year, making the ratios harder to get the older ones, PLUS the fact that people have been pulling since long before I started or ended.
Good luck to you though either way. :-)
