First, let's all agree that we search boxes of cents.
We aren't in England. We don't have a penny. Sorry, just a small pet peeve. I know the boxes are labeled pennies, but it doesn't make it right. Anyhow, the cents I enjoy searching as that is how I started my coin collection at 9. The halves can be rewarding, but very frustrating when you hit a skunk run. Sometimes, it just isn't worth the hassle and I take a break from halves, but the itch returns. Dimes are another favorite as they are easy and lightweight. Been filling glass cigar tubes for some time.
