How much heavier is platinum than gold?

Well I heard platinum is heavier than gold. I want to start collecting platinum coins. Is it more expensive than gold coins (since its heavier). How much heavier is it? Like lead?

An ounce of gold and an ounce of platinum weigh precisely the same.
For an equal number of atoms for each metal, platinum would weight 99.04% of what the gold would weigh.

Yes, you are
<< <i> Umm, I think you mean denser... >>
Yes, the greater density makes an equal volume of platinum heavier than gold. It would be kind of silly to compare the masses/weights of ounces of each

Heh, I wish. Wayy to expensive. I wouldn't be able to cough up thousands of dollars for a diamond. However, when I die, I have one request: To be made into a colored diamond via lifegem. They take your ashes and process you into a diamond! www.lifegem.com

<< <i>No I wasnt...look at what he asked..."which weighs more?" Platinum is a lighter element. >>
Oh, yes yes yes...I didn't read what you had said...
Platinum has a density of 21.450 g/cubic cm.
Gold has a density of 19.3 g/cubic cm.
So, if the two coins had the same volume, the platinum would weigh more than the gold.

Or, alternately, a 1 ounce platinum coin would be smaller than a 1 ounce gold coin......

Correct.
Put it this "weigh"

<< <i>Platinum weights slightly LESS than gold. >>
All of the coins are based on the same weight divisions. 1/10 , 1/4, 1/2 and 1 ounces. That does not change based on the metal.
Density and mass can change in relation to weight but weight can not change since it is a gravitational measurement.
Do you honestly think that GoldCoinLover's statement
<< <i>Well I heard platinum is heavier than gold. >>
had anything to do with atomic weight. He is asking about the weight of platinum and gold coins, not atoms.
Actually, not just gravity, but the acceleration of the object in question relative to whatever you're measuring it with.
How fast are the gold and platinum going relative to us?
<< <i>I think the intent of the question should read "given the exact same dimensions of two coins - one made from gold and one made from platinum - which would weigh the most?" The answer would be platinum.
Platinum has a density of 21.450 g/cubic cm.
Gold has a density of 19.3 g/cubic cm.
So, if the two coins had the same volume, the platinum would weigh more than the gold. >>
Some of you guys need to go to off topic. The fellow starting this thread had a legitimate question and all you did was make fun of his serious question. If you don't understand the scientific answers like this one why respond?

Who is making fun? I answered his question right off the bat, in the context I believe he was looking for. WELL???
<< <i>Is it more expensive than gold coins (since its heavier). >>
Yes - For Bullion coins and coins deriving most of their value from the metal content --- But not because it is heavier!!
No problem with most of your explanationssssss.
I dont know still what he was trying to ask. I gave a sound scientific answer and I was not making fun of him what so ever? I dont do that to people.
However, my answers are scientifically sound given the question asked. Not trying to start a war here. Just the facts please, just the facts.

<< <i>This thread feels like:
WHO'S ON FIRST
Russia made platinum coins back in the 19th century.
Some gold coins used to be hollowed out with cheaper platinum replacing the gold. This netted a significant profit.
For practical purposes round coins have only one dimension; diameter. Thickness in too dependent on striking and design characteristics to have much meaning.
Please don't get me started.
<< <i>Umm, I think you mean denser.

Actually platinum is both more and less dense than gold.
Platinum and Gold are Periodic Table buddies, meaning they are right next to each other. Gold is made when Platinum goes through the nuclear fusion process.
Using the Standard Atomic Weights, Gold is more dense than platinum and would therefore "weigh more", but there is an isotope of Platinum that is just a tad more dense the gold (with a Relative Atomic Mass of 197.967 vs. 196.966 for Gold)

I flunked out of NC State University in my quest for a BSME back in 1987. All this talk about Chemical/Physical properties is bringing back a bad state-of-vu. Could we keep it strictly on numisfacts here. Could we just say a one ounce Gold Coin is larger in volume than a one ounce Platinum Coin.
Weight: how heavy is something. It is dependent upon the local gravity. You "weigh" 1/6 as much on the moon.
Mass: How much stuff is there. Independent of local gravity. You have the same "mass" on the moon. Takes the same force to accelerate you to 10mph on the moon or the earth.
Atomic weight: weight of an individual atom of an element. Does not directly determine density. Au 196, Pt 195
Density: How much mass in a given volume. Au 19+-, Pt 21.5 g/cm3.
<< <i>While we are on the subject of platinum and platinum coins... Why does any country create platinum coins? As far as I know, no country has ever had a circulated platinum coin. If it were only for bullion purposes, why not just create different size bars? I am really curious to know the answer. >>
I plan to circulate a platinum coin as soon as I can afford to ose $800 on spending a 1oz coin. It would be great to see what the cashier does when you try spending it.

So, would a fat person jumping off a tall building hit the ground faster than a skinny person jumping off the same building? Or, just make a bigger mess?

1. Fat guy would cause more mess.
2. If scales were placed under both prior to them hitting the ground, there would be even more mess, and you'd have two broken scales.

1997 Platinum Eagles, right?
Are there any platinum patterns?
Wrong.
But your comment about platinum patterns puts you on the right track.
We'll leave this question open for a few more responses before I give the answer.
