"A penny saved is a penny earned."
--Benjamin Franklin

What if I told you that ol' Ben was underselling? Would you laugh? Would you call me crazy, then say a penny is about as useful as a screen door on a submarine these days? I'd wager yes on all three accounts!

Well friends, the simple truth is that Mr. Franklin, genius that he was, should have aimed a little higher. In point of fact, a penny saved is two pennies earned! It follows that four pennies saved are eight pennies earned, and sixteen pennies saved are thirty-two pennies earned. With a little mathematical reasoning, you can see how this could start to pay off: If you held in your possession a kind of legal tender, with an intrinsic worth equal to that of double it's face value, wouldn't you want to increase your holdings of this particular type of currency? Of course you would! It would mean buying a dollar for fifty cents, ten dollars for five, and one hundred dollars for fifty!

On Wall Street, an investment that offers a two hundred percent return is like a fairy-tale — something that stock brokers tell their children about at bedtime. What's more, you don't have to be a banking executive to know that if some money was worth double its face value, everyone would be scrambling to get their hands on it, right?


I know you're skeptical. I also know that, in these dishonest times, the unfortunate truth is that good people constantly have to be on the lookout for scams. But you just rest easy folks, and put your trust in Honest Earl. I'm the kind of guy that gals want to bring home to their mothers. My purpose is to educate, not to take your hard earned money, and I won't play you false!

Actually, pennies produced before 1959 were also made (primarily) of copper, as well. However, the numismatic — that is, collectible — value of such coins are generally greater than their metallurgic value, and therefore are not included in this discussion. For those interested in pursuing more information on the subject, your author has written the article entitled: Coin Collecting: Lincoln Wheat Pennies (History & Value), for which a link has been provided near the end of this page, under the Related Article(s) by Earl heading.

The Skinny on the Copper Penny

The long and the short of it is, that U.S. pennies produced from 1959 up until the second half of 1982, were made of ninety-five percent copper and five percent zinc. Afterwards, the Federal Government decided that it would be more cost-efficient to produce pennies composed of a zinc core with a thin layer of copper plating. Essentially, they decided to cut their operating expenses (At least, as far as coin mintage goes!), as copper pennies are more expensive to produce than zinc pennies. Incidentally, copper pennies are intrinsically worth more than their zinc heavy counterparts.

Here's what I mean:

Copper Penny Composition (1959-1982*)
Zinc Penny Composition (1982* onward)
Total Mass:
3.11 grams
2.5 grams
Multiplied by % (Cu):
Equals Mass of (Cu):
2.95 grams (Cu)
.0625 grams (Cu)
*1982 was known as a 'Transitional Year,' where half of the pennies produced were 95% (Cu), and the other half were 97.5% (Zn). **(Zn) also holds commercial value, but it is ignored for the purposes of this article.

A more precise calculation for the metallurgic value of a copper penny would also include the value of the mass of zinc contained within the coin (.01555 grams). However, I have not included this step for simplicity's sake. You can find the spot price for zinc using the same resource cited for determining the spot price of copper, as well as other metals such as gold, platinum and aluminum, at: — by way of the link provided under References, at the end of this page!

According to the above table, ninety-five percent of the total mass of a so-called "Copper Penny," is pure copper; or, 2.95 grams (Cu). It follows that, to determine the metallurgic value for a coin of this type, you simply must multiply the mass in copper contained within the coin by the spot price of copper. For example, the spot price of copper1 at the time of this writing is $3.29/453.592 grams. Therefore, the metallurgic worth in copper for the penny is:

2.95g x ($3.29/453.592g) = $0.0214 (Rounded to the nearest ten thousandth)

Or, simply put: Each copper penny, worth a face value of $0.01, actually contains $0.02 worth of copper. (Remember, there are 453.592 grams in a pound, my fellow USCU users!)2

Getting back to the pennies: From 1959 through the first half of 1982, the U.S. mint produced in excess of three hundred billion copper pennies.3 Many of these are still in circulation, and can be found everywhere that cash is exchanged for goods and services. This means that every time you get small change back from the supermarket, the gas station, the butcher, the baker, or even the candlestick maker, then there is a high probability you will receive copper pennies mixed among those coins. Many places of business will even have a "Take a penny, leave a penny" tray at the register, which are bound to contain copper pennies.

So, don't be shy! Ask cashiers and bank tellers if they have any rolls of pennies that they would be willing to part with (which you can sort through later), and whether or not they'd mind if you search their "Take a penny ..." trays. You will find that opportunities to snatch up these little copper Easter eggs exist virtually everywhere in our great nation. The simple truth is that most people see them as a nuisance, and are quite happy to exchange them for higher, more easily manageable, denominations of currency. In fact, you'll find that the response you receive to ninety-five percent of your penny inquiries will sound something like this:

Here's a fun fact: Pennies weren't the only U.S. coinage to undergo compositional modification. For example, up until 1965, dimes and quarters were composed of ninety percent silver. Also, from 1942 through 1945, nickels were composed of thirty-five percent silver. These were called "War Nickels," as they were produced during the second World War!4, 5

"You say you'd like to exchange a one dollar bill for four rolls of pennies?? No problem, sir/ma'am!"

The Downside of Copper Penny Hoarding & Final Thoughts

Ok, I've given you the molasses, but now it's time for the castor oil! Here's the rub: You can't melt down U.S. pennies to extract the copper. At least, not yet. It is a violation of federal law to deface U.S. currency, and as long as those good ol' boys and gals in Washington decide that pennies ought to be used in our — arguably — antiquated system of legal tender, then that is how it's going to be! I could tell you that I know for sure the day is coming soon when the penny will be retired, but that would be a lie. No man or woman can predict the future, and anyone who tells you they can is either a liar or under network contract.

Copper Penny Sorter

Work smarter, not harder! Should you decide to step up your game, you'll definitely want to invest in a good copper penny sorting machine. Ebay is a great place to find a bargain! To that effect, here's a portal to the auction site with "copper penny sorter" pre-queued into the search field, for your convenience:

Also, it is important to realize that the monetary exchange value of copper will rise, and fall, depending on market conditions, as well as the principles of supply and demand. However, over the last quarter century, the price for copper has shown an overall upward trend.(re: 1) It is a major element of industry, and demand for copper in the developing world continues to rise. Demand for copper stateside is also high, due to infrastructure and development projects.6

What I can tell you is that investing in copper pennies seems like a safe bet. But I would add that any bet, safe or otherwise, is still a bet. Therefore, as in all things, I do not recommend putting all of your eggs in one basket.

Should you get a big ol' glass jar and place any pennies from 1959 through the first part of 1982 in it? Yes. Should you, as a hobby, trade in any loose change you can spare for copper pennies and toss them in that big ol' glass jar? You bet! You can even step up your game and purchase twenty-five dollars worth of penny rolls from your bank teller, in a neat little box, from time to time, and sort through them at your leisure! Then, re-roll all of the zinc pennies and trade them in for some more (Just mark the penny rolls you have already sorted, so you don't end up going through the same roll twice!). But, you should not convert all of your savings, take out a second mortgage on your house, or tap into your kid's college fund, just so you have as many copper pennies as you can possibly get your hands on.

So, happy copper hunting! But remember, if you ever feel like you're starting to come down with "Copper Fever," and you're getting close to stepping over the line, just remember some otherwise words uttered by that late, great, author of Poor Richard's Almanac:7

"All things in moderation."
--Benjamin Franklin

"Wait! Did Ben Franklin say 'All things in moderation,' or was it some Greek guy?? ... Ah, well."

**Disclaimer: As of the date of this writing, it is illegal to smelt U.S. pennies in order to extract raw copper, under federal law. This article was written in the spirit of investment, as in the gathering of a resource, in anticipation of the day where pennies have been taken out of circulation.**

      Interesting facts about the copper in pennies. I feel that they should discontinue making pennies - why produce a coin which will itself buy nothing? I think the problem comes with adding sales tax.

      Hey, thanks Peggy W! Yes, it certainly does take a lot of them — great fun, though!

      Very interesting article! I don't know if I will live long enough to see pennies discontinued from use in our monetary system and it would take mounds of them even at double the value to add up. Now just out of curiosity, I may just start looking for them. ☺ Voted up, useful, interesting and will pin this to my board titled "Do you know this?"

      At the very least, he'll get good exercise lugging those jugs around! Be sure to employ proper lifting techniques or an able-bodied grandchild, old timer!!!

      Hey Earl, I was watching Pawn Stars the other night when the old man was hoarding copper pennies in 5 gallon buckets, I think he's on to something, lol, good read, interesting.
