In 2005, a block of four Inverted Jenny exchanged for a single US ¢1 Z Grill: PIMCO skipper Bill Gross gave up his IJ for which he acquired only two weeks prior, for a record at $2,97m, for Sundman’s blue Z Grill for which Dan Sundman paid $935,000 in 1998. (Reuter, Google News) The uneven exchange has completed Gross’ US stamp from the 19th century – a feat no museum has accomplished. There are only two Z Grill in the world and the other one is owned by New York Public Library.
The Collectors Club, US Postal, Long Island Philatelics are all there. The convention center has expanded nicely.
