Vol. 4 of the 2016 edition of the Scott Standard Postage Stamp Catalogue (Countries J-M) contains almost 7,500 value changes. Almost all countries in this volume — Jamaica through Mozambique Company — show some value changes. Macao tops the leaderboard, with more than 1,800.
A partial examination of Malaya and its associated states produced almost 450 value changes. Increases are seen across the board, with noticeable jumps for occupation issues. The 1942 Malaya postage due stamps issued under Japanese occupation (Scott NJ1-NJ7) move up as much as 25 percent.
Collectors of Malaysia stamps will no doubt be pleased to see that the stamps of the Malaysia state of Sarawak, formerly tucked at the end of the Postage section for Sarawak in Vol. 6 of the Standard catalog, are now included with the rest of the Malaysia states in this volume. Specifically, we have moved the listings for the State of Malaysia issues for Sarawak after Sabah in the Malaysian States listings. Previously these stamps were listed with the other Sarawak stamps that were issued before Sarawak became a part of Malaysia.
