Uh, only Bugs Bunny values items in carrots. I'm sure you mean KARATS, lol!
Anyway, gold coins are normally measured in what's called fineness rather than karats. The principle is the same, but the notation is different.
Karat measurements are based on fractions of 24; e.g. 18 karat gold is 18/24 (or 3/4) gold and 1/4 some other metal, often either silver or copper.
Fineness measures are based on decimals of 1000. Often the decimal point itself is left off, so for example you might see either 990 fine or .990 fine; both mean 990/1000, or 99% gold.
Circulating gold coins were made of lower fineness metal because high-purity gold is too soft and would wear out quickly. From the 19th century to 1933, U.S. coins were made of 90% gold and 10% copper, so that translates to 900 fine. There's not an exact karat equivalent because 24 is not a multiple of 10; there's no exact karat fraction equal to 9/10.
Newfoundland $2 gold coins were struck occasionally and only during the period 1865-88. If you have an 1885 coin it might be worth around $200 to $250 for its gold content.
The Actual Gold Weight (AGW) is .96750oz of pure gold
About $325, for its gold content.
The Actual Gold Weight (AGW) is .04837oz of pure gold. All U.S. gold 1 dollar coins have the same amount of gold.
90% gold and 10% copper. Gold weight is 0.9675 oz.
The Actual Gold Weight (AGW) is .24187oz of pure gold.
depends on the condition usually around 1500!
This coin is worth more for its gold content than as a collectible. At current prices, it would retail for around $1,100.
It's not an official US Mint coin. Depending on what company made it and whether it's really gold, its value would be determined by the gold content and condition of the dollar.
With gold prices at $1000/oz most of these coins are worth more for their metal content than as collectibles, about $250 with average wear. The only exception would be if the 1881 coin has a small "CC" mint mark on the back; it's worth about $500 as a collectable coin.
$475 to $550 for its gold content. Worn coins would be at the low end of that range.
It depends on the year and condition. Some are only worth the value of their gold content, and others are valued as collectibles.
