Undated handout photo issued Monday June 29, 2009 by public relations company Watershed of dateless twenty pence coins recently produced by Britain's Royal Mint in error. The Royal Mint admits it's made a rare error, producing coins without a date on them for the first time in centuries. The mint said Monday that at least 100,000 of the year-less 20-pence coins, normally worth 33 U.S. cents at face value, slipped into circulation at the end of last year..(AP Photo/ Watershed/PA)
