It's a question that's been floating in my head for a while: Will newer modern coins have as long of an average lifespan as coins that were minted 30+ years ago? Why does the mint strike all their coins in such low relief nowadays? Take the new Jefferson nickels for example. I think they're terrible. I run my finger over an uncirculated coin and it's nearly smooth. I don't think it would even take 15 years in average circulaton before the designs are unreadable. And I could go on and on about my issues with zinc cents. Of course perhaps the sheer enormous mintage numbers make up for the casualties. I don't know. Just a thought.

I hear ya. I'd much rather hold pre-64 silver over clad coins anyday. And copper coins over zinc. It just feels like real money.
But, you may also be pointing out one reason to save them. Their survival rate.
Especially the zincolns. Look at the ones you pull roll-searching now. Some of them, I'm almost too ashamed to even re-roll.
Almost.

I completely agree. However, note that Liberty and Buffalo nickels used to be a week's wage (just kidding, but you get the point)! So they got heavily circulated. I don't suspect today's Zincolns or post-2005 "Jefferson-on-crack" nickels will pass between too many hands before ending up in a big change jar or a bank box. Anyway -- for this reason -- I don't think they'll wear much. But they certainly would wear down to nothing if a nickel were actually worth something today. I do get the feeling in 2011 we'll start seeing 1983 Zincolns spontaneously turning into dust. Then 1984 the next year, and so on...

Clad quaters,nickles,dimes are all tougher then silver ones and wear out much less in circulation.
nickle just wears better then silver. Silver is to soft
Eazy way to see for yourself is just look at early 40's nickles 70 years in circulation still going strong.
Now the new cents feel cheap, as if the copper is even thinner then it was in the late 80's

Thats what happens when you debase the coinage. Coins that felt like real money become nothing more than a slug of worthless metal. Wait till the nickel gets debased, its going to be a sad day.

agreed - especially zincolns. Also, I really don't like the new quarters with the parks. I think the designs are crummy. They try to jam a bunch of pictures on a tiny coin and it just looks dumb.

Quote: Why does the mint strike all their coins in such low relief nowadays? It has to do with the extremely high mintages and the high speed of striking need to produce that many coins. The old silver coins were struck at a rate of around 60 to 100 coins per minute (120 coins per minute when they were using the dual die setup in the presses. Now at 60 coins per minute that is 1 coin per second. During that second the feed fingers have to drop a planchet into the coining chamber, the fingers have to get out of the way, the obv die comes down and strikes the coin, the obverse die rises back up, the reverse die rises up pushing the coin out of the collar, the feed fingers come in and push the coin out of the way, and the reverse die drops back down. That is seven mechanical steps that have to take place in one second. Now when the coin is struck it takes a certain amount of time for the metal to flow into the recesses of the die. It is a short amount of time but it is a definite legth of time. If you increase the striking speed that means there is less time for the metal to flow. Then you have the problem that coppernickel is harder than silver and does not flow as fast. So how do you compensate for the reduced flow time? Increasing the pressure doesn't help because it doesn't make the metal flow faster. So the obvious answer is to lower the relief so the metal doesn't have to flow as far. Well todays coins are struck at a rate of not 60 strikes per minute, but 750 stikes per minute. That is 13 coins per second. So the time of the strike and for the metal to flow is no longer .14 seconds it is now .01 seconds. Obviously the relief is going to have to be a LOT lower.

That's what I meant to say.
Nice explanation Conder.

 Many good reasons why I collect older coins.

So in summation, future money will eventually take the form of a low relief "U.S.A." on the obverse, and "## Cents" on the back. No design, no reeding, no nothing ;-)

I just can't get into modern coins. (other than my beloved proof sets  ) But I'm not much of a businessman and will probably regret ignoring zincolns.

conder you are right on. These days it is about quantity and not quality. The same thing apply's with cars, furniture,and many other products that are made with inferior materials. I shudder to think what coin collecting will look like in the future. I think it will be hard to find the grades especially in circulated rolls.

Conder, did you work at a mint previously? You have pretty in-depth insight over this process down to the "how can I hire less employees?" kind of thinking.
And, no, I don't think coins will be SO plain in the future. They still have to account for counterfeiters. The cheaper the materials are that are being used, the easier it will be to counterfeit. It seems like a child should be running things instead....

Cu-Ni coins have already proven themselves to wear much less in circulation than silver coins.
Zinc Cents are another story. I think those actually cost the Mint money in the long-term versus using 95% Copper Cents.
A Zinc planchet may cost half that of a 95% Copper planchet, but it doesn't have even close to half the circulation life of a Copper Cent.
If they have to press five Zinc Cents to serve the circulation lifetime of one Copper Cent, how is that saving metal costs?
Given the low face value and quick deterioration, why not set aside a few nice spotless BU Zincolns?

No they actually make MORE money for the mint when that happens. Back in 1982 the copper cent blank cost .8 cents, the zinc blank .4 cents. When they made a cent they made .2 cents on the copper and .6 cents on the zinc (I am ignoring production costs) Now say over the life span of the copper cent they have to keep replacing the Zinc cents that corrode away and they have to do that five times. Not on the books they still show a .2 cent profit on that copper cent, but on the zinc cent they show .6 X 5 or Three Cents profit. Why because the corroded zincs just get tossed and don't come back for redemption. Yes it costs the mint Two Cents in metal instead of .8 cents but the profit margin is much greater.
