!!!Caution!!! Melting pennies will release Zinc Oxide fumes which cause flu-like symptoms including fever, chills, nausea, headache, fatigue, muscle aches, joint pains, shortness of breath, chest pain, and cough. Use a well ventilated area with power assisted ventilation to avoid breathing these fumes.



That being said, this is ring made from pennies. You can smelt the copper coating off leaving you with zinc. Pennies minted after 1983 are all made like this.



You don’t have to have a lathe to do this. You could always hammer the ingot flat and follow the nickel ring instructions. A surprising thing is how lite it is. My wedding ring is the same size weighing 8 grams. This ring weighs in at 3.





Step 1: Smelt

smelt 1 (sm lt). v. smelt·ed, smelt·ing, smelts. v.tr. To melt or fuse (ores) in order to separate the metallic constituents.

I placed 10 pennies on a spoon and heated them with a propane torch. The spoon was held with locking pliers, which was held by a wooded clamp. Once the zinc liquefied I removed the copper with a metal probe (I used a light tester I had near by).

I then poured it into a section of ½” pipe and let it cool off.

Step 2: Cut a Ring Blank

Here I machined the ends off the blank then drilled a hole through it. I chucked the same drill bit into the lathe. Next I wedged the blank on by placing a plastic bag over the bit. Finally the outside was machined.

Step 3: Size the Ring

To expand the blank I hammered it over a pry bar. I started out with a small bar then moved up sizes as the ring expanded. To get to my ring size I eventually had to hammer over a ½ socket bit.

Of course to get your size simply stop hammering once it fits.

Step 4: Polish

I evened out the ring with a file. I then spun it on a ½” socket bit and sanded it with 1000 grit then 200 grit sandpaper.

Lastly I buffed it on a buffing wheel.

Thanks for reading.

No it isnt. It is illegal to "deface" money. That means putting another 0 on a 10 and trying to pass it off for a hundred dollar bill. That kind of stuff. You can melt and mangle coins all you want. Look it up.

Apparently you didn't realize that melting coins is illegal us the U.S.

Really? Where did you get that information? Everybody assumes this, but how do you explain those penny stamping machines in every zoo in the country? They even have them in state parks, so surely the state wouldn't participate in defacing US currency, right? Here is the trick... It is only illegal if there is fraud involved. The law says if anyone "fraudulently alters, defaces, mutilates, impairs, diminishes, falsifies, scales or lightens" US currency then it is illegal. Look it up. Title 18, U.S.C. sections 331 and 475. There is no fraud in just melting coins. He isn't recasting it into other coins, so where is the fraud? Take a look at all the coin rings out there. Not one of them has been shut down for defacing currency for the simple fact that NO FRAUD WAS INVOLVED. Melt them, drill them, press them.... Whatever you want. People have been doing it for centuries with all sorts of currency, so I would think you would know there isn't a law against using coins in art and jewelry even if that requires melting or mangling them.

Okay those penny machines take one at a time you could stand the for hours and destroy a dollar.and yes not all the country is going to stand there for hours.and people could melt thousands of pennies then take it out of the country in copper bars.

Not likely. For one thing, there isnt any copper in pennies minted after 1983. So if you wanted to take the time to gather hundreds of thousands of pennies and then sort out everything older than 1983 and then melt those into copper bars.... I think you would find that you would make more money planning for gold than spending a hundred hours to gain $20 worth of copper.

Please dot do this, zinc is toxic, the phumes, temps needed to melt it. Constant contact with your skin can poision you. Not to menchen that it tarnishes in a day or two.

So wearing a ring of zinc will poison you? How bout if you coat it with a uv sealant, that should make it safe and keep it from tarnishing. Would this be a correct assumption or no? Just trying to help out the ones that are set on trying this. Always practice safety right.

I totally agree. Don't stay too close close to the zinc because if something happens, you got to be safe. Also, do it outside on concrete.

Concrete and molten metal could be hazardous. Concrete stores residual moisture and as the molten metal comes into contact with the concrete it evaporates the moisture causing pockets of steam underneath the still liquid metal that will burst and send hot lava everywhere.

Sorry, I meant something that will not harm public areas or your backyard.

Back in the Dark Ages we used coins to cast dental crowns. We called them "22 cent crowns" because we melted an indian head dime, two buffalo nickles and two indian head pennies to produce the alloy. It would be considerably more costly to do so now (maybe find some worn out, "dateless" coins cheap), but it yields an excellent gold colored alloy that is very resistant to corrosion & staining.

Sorry, that should have been "mercury head dime".

Just smelt the zinc into rods and sell it as sacrificial rods to protect water heaters and home plumbing....

Don't try this with UK "copper" coins, they are made of steel.

1. Get 1982 or before pennies because they are pure copper.
2. One pennies weight in copper is worth $0.025
3. Smelt Into Ingots
4. Sell for 2.5x the worth of pennies
5. Go to bank with money and get rolls of pennies
6. Repeat

???

7. Infinite Money?

I had an out of work friend try that with quarters, half dollars and big dollar coins. Yes, infinite money, but only about 25 cents an hour profit. It takes a while to sort through $1000 dollars of coins to get maybe $1 worth of silver. Much less profit with pennies.

Cool! I'll have to remember that. I've found more than 2 dollars in quarters in U.S.A. so far and I've only been here for around a week. Pennies, though are the easily the easiest coin to find on the sidewalk.
