Why not make coins magnetic?
This way all my coins would clump together in my pocket as well as being easier to stack. Coins for parking could be attached to a convinient place in the car and on a metal desk, coins could be used to hold down notes (or attach them to metal boards on walls, white
boards for example next to a note, buy food etc).
This would not involve any changes to the design of the coin, just a magnet inserted in the centre.

Plastic Slots, or even aluminium (from recycled cans). |
|
| |
Haven't we done this one over and over again? |
|
| |
Anyway, magnetic coins would gum up the works of every slot machine out there, including those parking meters, rather defeating the purpose. |
|
| |
I don't know if we have done it over and over... i searched to no avail. |
|
| |
Read above... aluminium slots... |

Imagine standing in a crowded elevator -the doors open- everyone starts to file out - you take a step forward and are suddenly yanked backwards! Oh no! You realize your pocket full of change attracted the pocket full of change on the guy next to you! Whatever will you do? |

The problems of putting high powered electromagnets in coins. Perhaps a weaker flavour would suffice? |

It's funny to think of someone winning a small jackpot on a slot machine, and then removing 400 quarters all in one clump from the pay tray. |

Actually the Canucks have this one figured out. With stainless steel coins, a small magnet in your pocket will magnetize the whole lot into a convenient clump. |
|
| |
except they are not all magnetic so you end up with a clump and some jinglers |
|
| |
steel touching a magnet turns into a magnet. for suitable magnets, I suggest disposed of sonicare brush heads. they have powerful small coin sized magnets on the bottom which can lift about 10 lb. more than enough to stick your change together. (if it were paramagnetic) |
|
| |
I can see the warnings on hard drives: 'Keep away from magnetic sources, including motors and money'. |
|
| |
No cellphones and change in the same pocket... |
|
| |
cellphones and magnets don't cause problems for each other. most all solid state devices are safe in magnetic fields, remember it is not a magnetic field that creates electric flow, but a CHANGING magnetic field. if you were to shake your coins or rotate them VERY quickly and very close to your electronic device then you might have trouble, otherwise you are golden. |
