    You're correct!! I believe you'll find the 90% alloyed Gold coins are generally rounded up for their Karat worthiness, being commonly sold as 22 Karat coins.

    And did you happen to notice that the more silver you add to the alloy the lower the hardness number gets ?

    Point being, if you took the silver completely out of the alloy and used ONLY copper - the hardness number would actually increase !

    When 4% silver, combined with 8% copper is used the hardness number is 190.

    But when 1.75% silver, combined with 10.75% copper is used the hardness number is 197.

    As I said, take the silver out and the coin gold gets even harder ;)

    That's why you should be out :)

    Doug, I liked your post a lot and didn’t want to criticize your research. On the contrary, it was very well done! My intention was merely to point out that the wiki article on “fineness” doesn’t mention 21.6 carat, however all other values are listed. And no, I don’t think such a small variance would change the results completely.

    I had the impression (not backed by extensive personal experience or research) that large gold coins tended to show more bag marks than silver dollars. If that's true, that might be what led people to make the assumption --along with the folk "wisdom" that gold is soft, period, regardless of how it's alloyed.

    If it's true that coin gold is harder than coin silver, and also true that MS double eagles are generally more dinged up than MS silver dollars, could it be because the greater density of the gold coins makes for harder and more damaging impacts?

    Or am I just off base on my assumption that gold is generally more dinged up than silver?

    To be honest, I don't know that it is, but I don't know that isn't either. I mean I've seen a awful lot of really dinged up silver coins, think about Morgans and Peace dollars. And they may well be the best examples to use for comparison purposes, for a couple of different reasons. One, dollar coins have never circulated well in this country, not ever. And the $20 gold coins never circulated well either. And two, with both, large numbers of them sat in coin racks in banks or in bags in the safes and vaults. In the racks neither would get a lot of contact marks, they'd experience wear but not contact marks. But in bags, since both are large heavy coins, and the combined weight of a given coin coupled with the weight of all the other coins above it in the bag striking a coin(s) below them - contact marks would be prevalent. And of course the same kind of thing would happen at the mint when they were minted - think of coin hoppers.

    And if you think about small denomination gold, the $2.50 and $5.00, you don't really see any more contact marks on them than you do any other coin.

    Lastly, I also have to wonder if the overwhelming perception of gold being such a soft metal didn't and doesn't play a part in the perceptions of many people that gold have a lot of contact marks - when in reality they don't have any more or any less than any other coin. I mean people just falsely assume they do because they falsely assume coin gold is soft.

    Of course I'm just thinking out loud here, what I mentioned above is factual information but what we're talking about are people's perceptions and assumptions.

    But regardless of all of that, it's kind of hard to argue with what I found once I started looking at which is actually harder - 90% silver or 90% gold. And what I found is that the gold is definitely harder, stronger, and longer wearing than the silver.

    But, like I said, if somebody can find something that says different - I'm ready and willing to listen.

    Lastly, think about that coin I posted pictures of, the AGE. Do you see it covered with contact marks ? There's only one answer - no. So ask yourself why it isn't ? I mean I carried that coin in my pocket with 4 quarters and a pocket knife - every day for 7 years. That coin was my flippin coin, and I used to flip it a lot ! Letting it land on floors of all kinds, carpet, concrete, wood, tile, linoleum, even asphalt roads and concrete sidewalks, hundreds of times, maybe more. And yet there's scarcely a contact mark on it. But given what it went through - why not ? I mean if gold is such a soft metal - wouldn't you think it would be ?

    So what does the fact that it isn't tell you ? And it wasn't the only one, there were 4 others that went through exactly the same thing for various periods of time.

    All I can do is say what it tells me, that coin gold isn't as soft and susceptible to damage as we have all always thought it was. And of course we must also consider that we all based our assumptions on basically one thing - that since pure gold is soft therefore alloyed gold is soft too. But it seems that isn't so at all.

    Hardness is largely irrelevant among equivalent items - what matters is force.

    What matters for gold coins is that they circulated far less than they were used for interbank transfers, which involves shipment by the mode of the day (e.g. heavy bags of coins in railroad baggage cars)...

    You better buy from a trusted dealer or be able to identify a few "tells" on the coins that tell you it isn't a fake, if you aren't going to buy a graded coin.

    Gold bags probably travelled more -- including overseas -- wherea mint bags might just say in the mint they were struck at.

    Maybe...and again, gold bags travelled more.

    I investigated and found the same as you've reported, many years ago, before collecting U.S. Gold "classic coins". As you've inferred, virtually everyone with whom I discussed/informed, only considered the malleability of pure Gold, disregarding the hardness of Work hardened Copper.

    THANK YOU, as always, for presenting important facts, regardless that the post is aged. Gold is currently a more discussed subject for purchase than Silver (among those with which I discuss investments).

    (1) Why are they discussing it now ?

    (2) Are they BUYING ?

    (3) What are they buying -- gold Eagles or buffalos, or classic gold ?

    1. For the same reasons many in the world are, creating shortages.
    2. When they can.
    3. Whatever moves them, and is available.

    It is difficult to locate quality purchases.

    There seems to be a problem with sellers of "U.S. Classic Gold". Established sellers have inventory shown with prices, but when I send an order for multiple items requesting an invoice signifying a "meeting of the minds", no response. One said they'd send an invoice at a differing price, I agreed, no invoice, I sent certified payment yesterday. Another relisted their items at significantly increased pricing.

    The subject was recently discussed in this venue on another thread, where the seller couldn't determine what price to ask for his wares, because of the fluctuating base metal price.

    I believe individuals shouldn't be in the "market", unless they've mentally solidified their position prior to entering.

    Indecisiveness creates discussion, limits contracts, and choices. I trust this caveat fulfills your requests.

    IM, you're saying that sellers are backing out of agreements to sell because the price is rising bigtime after you've agreed to buy the coin ?

    I actually wait to place my order on coins that had been listed for an extensive period, until the market reverses downward. I don't want to be known as a "cherry picker". But my sellers know that I recognize coins with value above the "norm", that will possibly CAC/upgrade.

    It's a challenge for me to locate those that have greater value than coins proudly posted on sites as this. With patience/effort coins can be found that other miss because of undergrading, or their cost is greater than expected for date/type/grade/pricing publications.

    The government announced that the strategic gold stockpile has risen in the past few months.

    We have a "strategic stockpile" of gold ?

    What's it saved for ? A run on Rolex watches ?

    We do have the Gold Depository @ Fort Knox (ask Auric Goldfinger about that :D) and the NY Federal Reserve's gold vault.
