Copper
It means that the Gold on the metal you have is actually Gold Plated. 120 stands for 1/20, which means since it is only a plating, it is only one-twentieth it's weight in actual gold.
Kennedy, not "Kenedy" And not gold, either. The U.S. never made half dollars from gold. Your coin is plated, so it's only worth the underlying metal value. The good news is that 1967 halves are 40% silver so you could get maybe $1.50 from a scrap dealer.
The gold plating is done by someone other than the U.S. Mint and adds absolutely no numismatic value. It's only worth as much as someone on eBay is willing to pay, but only being a 1994 dime, that won't be much.
the rumor that they have only one pot is a myth, the leprechauns want you to think they only have one pot so when you catch them you only ask for a single pot of gold in exchange for their freedom when in reality they probably have multiple pots of gold.
a lot Yes and no. It is gold and gold is very expensive nowadays, but it is only 10kt which means that it is 41.6% pure.
Only if the metal is gold.
Gold is not the only metal that does not rust. Copper is another metal that doesn't rust, and so is platinum and nickel.
18 k is 18 karat, which is 18 parts gold mixed with 6 parts of other metal to strengthen it. It is 75% gold. 10k is 10 parts gold mixed with 14 parts of other metal and is only 41.7 % gold.
because it is the only soft metal
you cannot turn any metal to gold you can only extract gold from its ores by washing and roasting..
Gold purity in jewelry is represented by how much -- on a scale of 24K being pure gold -- of the metal is gold. A 10K gold 'batch' will always be a 10K gold batch -- only 10/24ths of the batch is gold, whether solid or melted. And the same is true of a 14K gold 'batch'. In order to 'upgrade' 10K yellow gold metal to 14K yellow gold metal, the 10K metal must be melted, separated from whatever other metal is in the 'batch', then added to less other metal in order for the same gold to be 'upgraded' to 14K. Another option is to replace the 10K setting with a 14K setting.
It can be formed into a foil only one atom thick, which you can't do with any other metal.
Gold is a very soft metal. that's why rings are only made of ten to eighteen karat gold ,pure gold being too malleable.
I think the only metals which are not white are gold and copper. And definitely, gold is that yellow metal.
Gold -because it is the only metal.
It means it is 100% pure gold. The higher the Karat number the purer the gold.9 karat is the cheapest gold, as it is only around 41% pure.This is because its mixed with another metal such as copper.As the percentage of other metal mixed with the gold is reduced,so the amount of gold is higher.
Since gold is a metal (precious) you can of course detect it with a metal detector. But only if it isn't tuned to ignore gold. since every metal has a different phase response metal detectors with discriminators can be tuned to ignore certain metals.
