It would probably be worth a few dollars to a collector who cannot get one of the 4 genuine Confederate half dollars which are valued in the hundreds of thousands, the 500 official "restrikes" made on previously struck US half dollars valued in the 5-10,000 range, or the 500 "Scott Tokens" which used the original Confederate reverse die valued up to $3000 or so.
About $33,000
The short-lived Confederate States of America only issued two coins, the one cent and the half dollar. A genuine Confederate half dollar is so rare that it does not have a listed value. A number of restrikes were made decades later which run from a few thousand to tens of thousands of dollars in value depending on their wear.
The value is very little or nothing. Reproductions have no numismatic value. Please note that the Confederate States of America never made any gold coins.
The value of a fake twenty-dollar Confederate States of America coin is generally minimal, often just a few dollars, as it is considered a novelty item rather than a collectible. Authentic Confederate coins can be worth significantly more, but counterfeits lack historical value. Collectors typically seek genuine pieces, and fakes may be worth only the cost of the metal they contain, if any. Always consult a numismatic expert for precise valuation.
$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.
Probably nothing. The Confederate States stopped issuing money in April, 1865. The date in the question is 102 years after that date. In the 1950s and 1960s it was not unusual to find ads for wild amounts ($1000, $10,000, etc.) of 'real' Confederate money for one dollar, with the ads placed in comic books.
One Kauai dollar of Hawaii is equivalent to one United States Dollar of all United States of America.
AnswerThe CSA only issued a small number of low-denomination coins. What you have is almost certainly a fantasy piece with little or no numismatic value.
Your coin is either a copy, a fantasy piece, or a counterfeit. All 4 of the genuine Confederate half dollars and the 15 one cent coins are dated 1861
There was no Confederate money in 1845.
A one million dollar note from the Confederate States of America is considered a novelty item and holds historical significance rather than intrinsic monetary value. While these notes were issued during the Civil War, they were never backed by real currency and became obsolete after the Confederacy's defeat. Today, they can be valued by collectors, typically ranging from a few dollars to several hundred, depending on their condition and rarity. However, they do not hold any purchasing power.
Nothing, because the Confederacy no longer existed in 1867.
