Benjamin Miller built his collection surprisingly late in life. He didn’t start stamp collecting seriously on a large scale until 1918, when he bought one of the famous inverted “Jenny” stamps at the age of 61. After that, he intensified his collecting, writing articles in stamp journals and purchasing from up to 30 dealers.
By the early 1920s, Miller was well on the way to his ultimate achievement: collecting one example of every U.S. postage stamp in the Scott catalogue of his day. But he collected many varieties, tooÃ¢Â€”color shades, frauds and forgeries, fresh unused stamps, and varied cancellations. Miller also enjoyed “plating” stamps, seeking one copy for each position on a printing plate.
