China News Service, April 26, reported that the prototype of the U.S. one-dollar coin, a copper coin minted by the Philadelphia Mint in 1794, sold for 840,000 U.S. dollars on the 24th, much higher than previous estimates.

  Bradley, a spokesman for the Highland auction house, said that this copper coin is very similar to the silver coin later minted in Philadelphia, but is famous for missing the outer circle of stars.

The original owner was Simpson, the co-chairman of the Texas Rangers baseball team. The original estimated price was $350,000 to $500,000.

  Lipson of Highland Auction House stated that this starless coin was regarded by collectors and related institutions as a unique prototype of the later silver dollar.

Its front is printed with the Statue of Liberty with flowing hair and the year 1794, and the other side is printed with a wreath surrounding a small eagle standing on a rock.

  Lipson pointed out that it may be because the coin has been buried in the original site of the mint, the pattern has been corroded, and it is not in perfect condition. The brown surface of the coin has some scratches and other marks.

  According to the auction house's statement, the coin has been changed hands eight times. Simpson, now 73, purchased this coin and other coins as a collection in 2008.

He said: "Coins should be appreciated as works of art, and I get infinite pleasure from them."
