In the United States, the practice of marking gold karats began in the late 19th century, with the introduction of standardized gold purity markings. The Gold Standard Act of 1900 further established a framework for gold purity and karat values, leading to more consistent labeling. By the early 20th century, it became common for jewelry manufacturers to mark their products with karat values to indicate the gold content accurately.
The US gold Liberty Head coins are actually 90% gold (21.6 karats), and the current gold values which the coin values are based on are $5 (Half Eagle) $340US and $10 (Eagle) $680US, respectively.
No. All US nickels minted in 1941 contained 75% copper and 25% nickel. If you have one that appears to be made of gold it is probably gold plated or colored with some other substance to give it a gold appearance. Sometimes with nickels that have not been circulated [used in everyday business] tarnish can develop and at times this can give them a golden like appearance depending on the environment they have been in. Also there are chemicals that can be used to create a tarnished look on the uncirculated coin.
Retail values for 1852 Liberty Head gold dollar coins run from $126.00-$270.00 for circulated examples. Uncirculated start at $288.00
Sorry no US gold coins dated 1917 were struck
No. The US did not make any gold coins for circulation after 1933. There are no gold nickels.
Sorry, but karat (purity marks) do not go that low. In the US, if it is less than 10K, it cannot be marked as gold. Likely that is a manufacturer's mark- there were several makers of nice costume jewelry that did use that marking.
Gold and sterling silver are two distinct metals with different properties. The marking "525" typically indicates that an item is 52.5% gold, which is equivalent to 14 karat gold. Sterling silver, on the other hand, is composed of 92.5% silver and 7.5% other metals. Therefore, the marking "525" is more likely to indicate gold rather than sterling silver.
Any company selling Jewelry in the US is required by law to engrave the purity of the gold. If you have a magnifying glass, look on the inside shank of the ring and you should see either 10k, 14k, 18k, 22k written on it.
No. US nickels have never contained any gold. For one thing, even when the price of gold was much lower a gold coin the size of a US nickel would have been worth several dollars; today it would be worth hundreds.

It is a statement of purity. It means 375 parts per thousand or 37.5%. This is equivalent to 9K (karat). There are three ways to indicate the purity of precious metals: 1) as parts per thousand, 2) as a percentage and 3) in karats with 24K being 100%. In the US and Canada, it is most common for the purity of gold and platinum to be shown in karats and for silver to be in parts per thousand.
European jewelry makers have a different way of marking the purity content of jewelry than does US makers. 325 on Italian gold means it is the equivalent of 9K in the US. It is not a high quantity of gold, but it does still contain (likely) 32.5% gold and 67.5% other metal(s).
Gold jewelry in Portugual must by law be 19.2 karat pure, there fore the marking of 800 translates to 80% gold, or 19.2 parts out of 24 (24 parts being 24 karat gold, 100% pure). A lot of European gold jewelry is marked 750, which ranslates to 75% gold content, or 18K, 18 out of 24 parts gold. Gold in the US is typically 14K or 58.5% gold, which is represented by the mark 585, 417 is 10K, 41.7% gold. Hope this helps.

formula for calculating worth worth = GP/24*k*w keys GP= present gold price in OZ/gm get it from here http://goldprice.org/gold-price.html K= karats of your gold jewelry W= weight of your jewelry in OZ/gm ----------------------------------- As price changes every day , worth will also change. So calculate it by yourself.
Gold is measured in karats whereas gems are measured in carats. The higher the karat the more pure the gold is. You can buy whatever karat you it just depends on your location, eastern countries and Indian sell 20k to 24k gold whereas in the US the most popular is 14k you can tho find 16k and 18k. Pure gold is 24K, but as you go to higher K gold, you also get softer material, which is easily damaged through normal usage.
They started getting cash for gold metal as soon as they started selling it. Gold prices are up. The cash pprizes goes with the medal. For US is $25000.00
