But, whether or no, the fact remainsthat after the first few issues of postage stamps had madetheir appearance without perforations, the rows of holesbecame almost universally accepted as a necessary partof a postage stamp. There is, of course, a very apparent difference betweena stamp without perforations —"imperf."— and one withperforations—"perf."—and one can readily understandwhy early collectors made such an important point ofthat difference. However, in this day of collecting it issomewhat difficult to understand why so much emphasisis placed on the different gauges of perforation {seepage 71). The fact remains that for United States stamps,which have been perforated by machines producingvarious gauges of perforations, there is often an enor-mous difference in value running from a few cents to asmuch as several hundred dollars for what, to all intentsand purposes, is the identical stamp except for the gaugeof the perforation. |
