EXTREMELY FINE MINT NEVER-HINGED EXAMPLE OF THE EXTREMELY RARE WIDE TOP PLATE BLOCK OF THE 50-CENT CLIPPER ISSUE.
Advanced collectors of U.S. plate blocks understand that this issue is far rarer as a wide top Mint N.H. plate block than even the $2.60 Graf Zeppelin. There are perhaps 10 or fewer Mint N.H. examples extant. The Scott Catalogue notes "wide full selvage top margin plate blocks of No. C22 are extremely scarce and sell for $3,000.00 or more..." (versus $85.00 price for regular plate block).
