You are bidding on a 2004 PCGS MS66 20% Double Clipped Keelboat Nickel Mint Error Rainbow Toned Rare Date.  Errors are becoming very rare as the mint has put in systems in 2002 to virtually stop all majors errors from getting out of the mint. Please check my very positive feedback. Shipping and handling $2.95. Please check out my other ERROR COIN Auctions this week.
