not until 2012. and it is for the 5c piece only.

 

Anyone have a link for this info?

 

it has not yet been made public as the mint has not agreed upon a cost effective alloy to replace nickel. their current choice is a synthetic plasticizer that contains petroleum derivatives, which is counter intuitive for a nation trying to appear as if they are trying liberate themselves from black gold.

below is the comp. data for current and past nickel alloys used by the us mint.

boo , US using more garbage metals to produce lame coinage

 

Start saving nickels?

 

HR 3330

Still pending. Only proposed
You know Congress, they cant get a single thing done!

 

Maybe they will make them out of the same composition as the new Pres dollars.
Only this time they will include the chocolate!

 

my wish

i hope our new cent and nickel will be like that of canadian. it can maintain its size and color. and a little reduction on its weight.

 

:mouth:

lol

 

new nickel

or just change the nickel from cu-ni to brass at the same size and weight.

 

How about something even MORE wirhless like wood?
I always liked the wooden nickel!

 

wood vs: aluminum

i will choose aluminum rather than wood.

 

Oh No a wooden nickel:goofer:

 

And nickel plate them like they do the cent planchets today so the average Joe in the street will never have a clue that they change was made. (There are still people out there that think the coppernickel coins have silver in the outer layers, an a lot of people never realized that the cent was changed to zinc because it still looks like copper.

Two hundred years ago the population was so in tune with the value of the metal in the coins that they exported silver dollars because of a .5% premium of metal over face, and today they blithely spend coins with a metal content nearly100% over face

 

welcome to electronic banking and the marketing of Visa. coins are worthless and cash slows everyone down.

-Steve

 

I'm picturing a bleak future of really lightweight coins with outer materials which oxidize immediately. eew. The real "problem" is the crashing value of the dollar. If the dollar was back to where it was 5 years or so ago this discussion wouldn't even be taking place.

 

color nickel and cent

why not colorized the aluminum based nickel and cent?. just paint cu-nickel color on an aluminum nickel size coin. also paint copper color for aluminum cent.

 

That's a huge and important change in mindset. You hear people say things to the effect that we "can't afford" to make coins from silver or copper without stopping to think that maybe it was the weight of the silver and copper that gave the coin its face value in the first place. I'm sometimes amazed how people actually think that it is somehow necessary for coins to have an intrinsic value less than the face value. I guess someday it will all be electronic anyway.
