US $20 gold coins are made of 90% gold, which puts it at about 21 1/2 kt.
It means that is it 18 kt gold. XXX = .750 or 18 kt. Hope that helps.
These items are solidly encased in plastic and are in a dark blue case with gold trim and an eagle on top. The 1999 set, which contains a penny, nickel, dime, quarter, and dollar, was listed on eBay today (Sept 22, 2009) for as little as $4.95 and as much as $24.95.

Gold - or just Golden?If you have a gold-colored Sacajawea dollar minted since 2000 or a presidential dollar minted since 2007, it is worth one dollar if you found it in change. If it's in uncirculated condition or a proof coin in the original mint packaging it might retail for $2 to $4. Ordinary Sacajawea and Presidential golden dollars that you get from a bank are struck from a composition of copper with a manganese brass cladding that gives it a golden hue. Their actual composition is 88.5% copper, 6% zinc, 3.5% manganese, 2% nickel, and are NOT rare. Feel free to spend them.But if you have a 22 kt. gold dollar coin from the 1800s, it could be anywhere from a couple of hundred dollars up to a six-digit figure, depending on its date, mint mark, and condition.
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.
The 2006 American Buffalo $50 gold coin was the first US coin to be struck in 24k gold. Other mint issue gold coins, $10, $20 etc are aproximately 21k, containing 90% gold.
The plating adds nothing to the value of the coin.
The 1991 $20 Desert Storm pieces from the New Queensland Mint have no numismatic value. Also they are not legal tender in the U.S. As for value, do a google search.
A denomination is needed, post new question.
No, sometimes there is also 24 kt gold.
rgp 10 kt means its "rolled gold plated" of the 10 kt variety
The standard for all gold American circulation-coins from 1837 to 1933 is 90% gold and 10% copper, so the coins are 0.900 fine which is 21.6 kt of pure gold.
Pure gold is 24 kt. 14 kt gold is (14/24)=.5833 pure. Multiply by 100 and it is 58.33% pure.
Yes, but it is usually jewelry made overseas (in India, for example).
24 karat gold is 100% pure gold. There is no such thing as 28 karat gold.
23.65 Kt, that be a lot of karrots.
10 kt gold is lighter yellow than 14 kt gold
