Introduction: How to Make a Coin Into a Pendant
Last winter, one of my best friends and I went traveling through Europe together. It was definitely a memorable experience and for her birthday this year, I wanted to give her a memento from our awesome vacation. I had this 10 cent coin from our trip that I turned into a cute necklace for her to wear and remember our all the fun adventures we had.
This is a simple, heartfelt gift that makes a unique and inexpensive souvenir for any trip!
Step 1: Materials
Here's what you will need:
- coin (I used a 10 cent euro, but you can use anything)
- a chain in the length of your choice (I got a chain that already had the clasps attached but you can make it yourself if you want)
- a jump ring
- drill with small drill bit capable of drilling through metal (I tried to use a metal punch at first, but it wasn't strong enough to punch through the coin)
- pliers
Step 2: Make the Hole
I first tried to make a hole in the coin using a metal punch, but the coin was too thick and it didn't work :(
I ended up going to the hardware store and getting a small drill bit specifically for metal and that ended up working great. I used vice grips and a clamp to hold the coin in place while I drilled. I didn't want to damage the surface of the coin so I used the cardboard packaging that the drill bit to wrap around the coin while I was drilling it.
I drilled through about halfway through the coin, then flipped it over and drilled through the rest of the way. This method kept burs to a minimum, which made finishing the coin a lot easier.
Once you have a hole all the way through your coin you might need to use some sand paper or de-burring tool to smooth out any rough edges on the hole.
Step 3: Add the Jump Ring
I used my pliers to open the jump ring and slid the coin onto it. (Jessyratfink has a great tutorial on this you can find here.) Before I closed the jump ring I attached it to the chain since the closures on the chain I got were too small to fit through the jump ring after it was closed. I actually like that since that means the coin won't slip off accidentally.
Step 4: Presentation
To give this to my friend, I got a nice ceramic box to present it in. I used a piece of foam from another necklace I bought and traced the outer diameter of the box onto the foam using a silver eyeliner pencil so it would show up on the black foam. Once I had traced it, I cut it out using heavy duty scissors. It's ok if the circle isn't perfect, since it will be squished into the box it will look fine. The foam I used already had two slits in it that I strung the necklace through to keep it in place inside the box.
Step 5: Give Your Gift!
I slipped the necklace through the two slits and then stuck the foam into the box with the excess chain from the necklace underneath the foam. It's an easy way to showcase this simple necklace and makes the whole gift that much more special!

This is great! My father gave me a good bunch of coins from when he was in the military. They would make a great bracelet. Thank you for sharing this great Instructable!

Oh man, make sure none of them are valuable on their own, and then make an awesome bracelet and please post it as an Instructable if you do! I bet it will look super neat!

Who cares if it's illegal. it's pretty cool. I doubt the illegality of something this trivial.

Thanks! I wasn't too worried about the legality of drilling a hole in a ten cent piece of metal :) haha

I like it! Rather than using sandpaper on the edges of the drilled hole, which might make a mark you can see, or buying a deburring tool, just use a slightly larger drill bit. You can just spin it a couple of times to take off the edges and you can just do it with the drill bit in your hand, it won't need much spinning. As for it being illegal in some countries, it's usually only illegal with their own currency. They don't usually care about other countries bits of shiny metal. I suspect they wouldn't really be that bothered with a 10cent Euro anyway, which I presume is made out of recycled 2CVs.

That's a good idea too! By drilling halfway through and then finishing it from the other side I actually didn't have any burs or rough edges, fortunately, but your milage may vary, of course.
As far as the legality of this project, I have no idea, but I'm not too worried. I don't think my friend will try to buy anything with it. I'm American and I think the only laws that exist here are about banning making currency look like other currency, for example turning a $1 into a $100. But again, I am not 100% sure on that, don't blame me if you get arrested! haha

This is illegal in some countries.
Cool idea though :)

Well, Danger isn't my middle name for nothing! ;) haha

No it certainly isn't...

...but it was Danger Mouse's first. I'm not sure what his middle name was- or if he had one.

I'm still super impressed with the way you did the foam pad - it looks so professional in the box :D
Reply 8 years ago on Introduction
Thanks! The foam was remarkably forgiving, as you can see from the lopsided circle shape I actually cut it into, haha
