[2] Phillips wrote numerous philatelic articles, including those published in The Gibbons Monthly Journal, The Stamp Advertiser and Auction Record and the Gibbons Stamp Weekly where he wrote articles on various collections he had helped build or sold.
In 1922 Phillips sold the Stanley Gibbons business and emigrated to the United States, establishing his headquarters in New York City.
There he continued his practice of selling stamps to help collectors build up their unique collections.
Many of these articles dealt with famous members of the stamp collecting community and are of a historic nature.
And, in 1941 he was named to the initial list of the American Philatelic Society Hall of Fame.
