Friedberg 1185. 1906 $20 Gold Certificate. PMG Choice Uncirculated 64 EPQ. Serial Number 1. Here is an incredible Gold Certificate and another fantastic trophy note from this monumental collection. This was the very first Parker-Burke 1906 $20 Gold Certificate, as seen by the boldly printed golden serial number H1 found at the lower left and upper right. The engraved design elements are all boldly printed in sharp detail on this well margined and crisp example. This note can be traced back to the remarkable collection of Albert A. Grinnell. It was featured in Barney Bluestones part-2 sale of the A.A. Grinnell collection in March of 1945. As noted, Grinnell was a partner in the Grinnell Brothers chain of music stores based in Detroit, each with a showroom of pianos, musical instruments, sheet music, phonographs, radios and other items. Albert was alone in his study and pursuit of federal paper money, without much if any knowledgeable competition (in contrast Col. E.H.R. Green hoarded paper but did not study it).Bluestone, based in Syracuse, New York, entered the auction business in the 1930s and handled many rarities. His catalogs are so elusive today that the items he handled have never been carefully studied. <em>From Albert A. Grinnell; Barney Bluestones sale of March 1945, lot 753; Heritages sale of January 2005, lot 17828. </em>
