we need to know what the coin is.
Repost with a description of the legends on the coin along with diameter and weight.
Please report back to me and tell me the coin's denomination - is it a quarter eagle, a half eagle, etc. (?) and the coin's mint state.
no
British gold coins of that era did not have values marked on them. The only way to tell the value of such a coin is by it's size.
$20 gold coins minted by the Confederacy had the name of the United States on them so it is impossible to tell which coin they minted.
There are many on line just type in the date and denomination of your coin and a whole bunch will pop up.
If the coin is made from gold, it will say so on the packaging it was sold in.
It's not possible to tell without knowing the coin's denomination and whether the holder is actually connected to the coin. If it was soldered on, for example, it would damage the coin and reduce its value somewhat. The good news is that gold is now so high in price that the coin is probably worth more for its metal content than as a collectible.
A 2 peso coin from the Philippines has a face value of 2 pesos. Depending on the year and specific issue, some 2 peso coins may contain a small amount of gold, but most are primarily made of nickel-brass. The gold content in these coins is typically negligible, as they are not primarily intended for investment purposes. For accurate assessments of collectible value or specific gold content, it's best to consult a numismatic expert or reference catalog.
You can look coin's up in a coin collection book. And get an ideal of it's worth. Most pawn broker's would be able to also tell you some information on your coin.
Quarters ad dimes, and lager denominations of coins, used to be made of silver, and a few of gold. The value of each coin was basically determined by the value of the silver or gold used to make it. Some people used to shave bits off each coin they received, thus accumulating valuable silver and gold for resale while reducing the real value of the coin being shaved. The milling on the edges was added so that you could tell if someone was trying to palm off on you a coin that had been shaved that way and was, therefore, not worth the amount marked on it.
Send it to a coin expert and they will most likely be able to tell you what it is worth.
You need to provide a lot more information. As you could tell by reading other posts in this thread, to determine the value of a coin you need to know its denomination, date, condition, and mint mark just for starters.
