Frederick John Melville,
Chats on Postage Stamps
“ In the cases of stamps of the larger countries which have had a long period of currency the rise is slow, but the frequency of the occurrence of unusual circumstances which cut short the life of a stamp on the active postal list has introduced a sporting element into even the collecting of current stamps. But it is inevitable that, with the retirement of a postage-stamp from use, there must come sooner or later a stoppage in the supply at the normal rates prevailing during its period of currency. ”
