You BOZO! You really think the government made coins for blind people. Then why excactly is the keypad on a driveup ATM have “Brail Writting”??? Its not because blind people drive up to it!! It’s because that is the way the numbers were made in the first place.

gold is a soft metal. fake coins were made of iron. biting a coin indicated if the coin was real because a tooth would sink into gold but not iron.

I’d be interested to know why they stopped making the coins out of gold and silver.

Ok, wat u say may b somewat true, but the reason they still have those edges is not because ppl r used to it, but because some ppl need it. Blind ppl that is. it’s how they can tell wat coinage they have. If u’ve ever seen Daredevil he folds his bills differently according to their worth, so he can find them later. same thing with coins, except it’s kinda hard to fold a coin a certain way . anyways, there’s the truth of it

Different edge types on coins is also a very simple yet effective method of making currency easier to use by the blind. All of the new Euro coins were designed specifically with this in mind.

It’s called inflation. It became too expensive to ACTUALLY use gold and silver. They started using substitutes (copper, zinc).

It’s because the gold was in the middle and silver on the outside made it hard to tell how much gold was actually in the coin. People couldn’t see the thickness or quality of the gold in the middle of the coin, so they bit the edges of the coin to see how the newly scratched coin would shine in the light. Then the government stepped in and made ridges so people wouldn’t have to bite the coin. You probably seen people do this to gold coins in old movies. I think my conclusion is right, please prove me wrong. What do you think?

Thanks Lacey. From your message I´m guessing you´re one of these “blind ppl”. You can get a braille keyboard you know, instead of just mashing the keyboard.
