What coinage would you stop to pick up and why?

I pick-up pennies, 'cause I can make bullets out of them when the zombies come ................

Sentago's. They are worth 1- 200 a American cent. But we use them to play cards here with. Been on a loosing streak. Must be down $2 or more now. So running low on them.

A 1943 copper Lincoln head penny.

I pick up all coins and other currency. I have lately been picking up coins and depositing it int charity boxes. But I can't say it amounts to much.

Even though the currency is devalued, there are still too many times when I've been in line and needed that nickel or dime to avoid having to break a $20. I will pick up anything that has a silver color to it. And over the years, I've gotten very good at spotting the slight color difference between a copper-plated zinc cent 1982 or later and a bronze cent 1981 and earlier. I keep every bronze cent I find in my change, they have two cents in copper. So I will pick them up unless my hands are full. And if it is a newer one, it's once cent I didn't have before. If it's turned white, I know it's a corroded zinc and those I will pass on.

If my arthritis isn't too bad that day, ill still pick up pennies. Otherwise it's gotta be at least a dime.

Nothing less than a one ounce Krugerrand
