Mint N.H., brilliant color, post-office fresh, tiny perf flaw at bottom not noted on certificates
Our comprehensive census of Scott 509a, which includes all of the records of the Philatelic Foundation, contains 21 used copies and this single unused example.
Ex Blumenkopf. With 1994 A.P.S. and 1995 P.F. certificates. This issue is massively undercatalogued in Scott. For example, Scott 511a, which is readily available in unused condition (five Mint N.H. are in Power Search), catalogues $7,500.00.
