gold karats what are there values
Such a coin does not exist. In the event that somebody did produce a gold Halfpenny, it would be worth whatever the current bullion value of gold is.
More information is needed. What country or private mint issued the coin? How much gold does it contain by weight?
A karat is a measure of purity, not weight when it comes to gold. A piece of jewelry with 1 karat gold would be 1/24th gold by weight.

gold karats what are there values
It depends on what coin you are talking about. If you are talking about the Eagle coin, with a denomination of $10, produced in the 18-1900s, you are looking at a couple thousand dollars. However, the exact value depends on condition. Then there is the American Gold Eagle 1/4 oz $10 coin, this is worth about $500. It is about 8 grams, and 22 karat gold. Then there is the American Buffalo, it is 24 karat pure gold, that would be about $700, it is a 1/4 oz $10 American, or simply Gold Buffalo. These have no numismatic value, only bullion value.
