We usually think of coins as something we use for change or small purchases — but did you know they can do a lot more than sit in your wallet?

In fact, there’s a surprisingly useful trick that involves something as simple as placing a coin in your shoe. It might sound odd at first, but once you understand how it works, you’ll see why so many people are giving it a try.

Here are some amazing ways coins can help in your daily life, from getting rid of smelly shoes to helping your houseplants thrive!

1. Say Goodbye to Smelly Shoes

Ever take your shoes off and instantly regret it? Bad odor in shoes is usually caused by bacteria and moisture. But here’s a quick fix:
Put a couple of copper coins inside each shoe overnight.

Why does this work?
Copper releases ions that naturally fight bacteria and mold, which are the main culprits behind that unpleasant smell. By morning, your shoes will smell fresher — sometimes after just one night!

2. Keep Feet Drier and Fresher

If you struggle with sweaty feet, copper might be your new best friend.
Copper helps control humidity inside your shoes and can even stop fungus from spreading.

Tip: Drop a few copper coins into shoes that tend to trap moisture. Over time, they’ll feel drier and fresher.

3. Help Aquatic Plants Stay Clean and Healthy

Just add a nickel coin into the water container.
Nickel slows down bacteria and algae, keeping the water from turning cloudy and your plant looking healthy.

Remember to swap out the coin every couple of weeks for the best results.

4. Make Tape Easier to Use

Struggling to find the end of the tape roll?
Here’s a simple hack: Place two coins on the tape’s edge — one on top, one underneath. Then, gently slide them in opposite directions.

5. Auto-Stop Incense or Mosquito Coils

If you burn incense or mosquito coils and want them to stop at a certain point, just place a coin where you want it to end.

The coin absorbs heat and causes the coil to burn out exactly where you placed it. No more burning it down completely or waking up to smoke!

6. Keep Plant Water Clear

Similar to aquatic plants, if you keep cuttings or herbs in water, a coin can help keep things fresh.
Just drop one in the jar — it’ll slow down bacterial growth and keep the water from getting cloudy too fast.

Extra Tips for Best Results:

• Choose copper or nickel coins — they naturally fight microbes.
• The wetter the shoes, the more coins you can use.
• Replace coins in water every 2–3 weeks for full effect.
• Store a pair of coins next to your tape roll for easy access.
• Avoid using very old, dirty coins in shoes or water containers.
