I do collect fakes (of the legal variety) - but this one is actually illegal as it is, so it is valueless at present.
The coin is a copy of a US pattern
Trade dollar and it was produced in China very recently (within the past 2 years). These sell for $1 each - or less depending upon your source in Hong Kong. The Copy is illegal because it does not have the word COPY engraved or stamped on it in accordance with the Hobby Protection Act.
The coin is not legal to import into the US and it is not legal to sell until the word COPY is added. Because it is a copy of a "Pattern" and not a copy of an actual monetary item, I am uncertain about the legal status of simply possessing the coin. But I would add the word COPY ASAP.
