That's really an open-ended question. It could look like whatever double eagle that's being copied - Liberty Head or St. Gaudens, or it could be a fantasy piece or bad fake that doesn't resemble any known coin.
If it's a legitimate replica not intended to be passed off as a counterfeit, it would look very much like a genuine double eagle but would have the word REPLICA or COPY worked into the design somewhere, as required by law.
The twenty dollar coin is known as the 'double eagle' and has been of two designs- the first, minted from 1846-1924 depicted the head of Liberty on one side and the Seal of the USA on the other.
The second, minted from 1924-33, depicted Liberty rising in triumph on one side, and the US eagle flying across a rising sun on the other. The eagle was designed by the famous American sculptor Augustus Saint-Gaudens.
Both coins are made of almost pure gold, so have a dull yellow-gold appearance. The coins began to be re-minted in 2009- early examples can fetch as much as $720 today.
