Varieties, errors and flaws

Abstract

Mr. Rostron said that he started collecting stamps as a child and soon acquired the first 1,000. As the collection expanded, so did knowledge about different watermarks, colour shades, perforations etc. The need to re-layout his collection became apparent. Now, after a lifetime of collecting stamps and many further collection re-layouts, it has only served to emphasise to him the magnitude of the subject. Designers and printers over the years have taken a pride in being accurate and correct. It was probably due to their success that caused collectors to examine the product very closely. As a result, apart from known varieties, more were discovered as well as errors and flaws. It is hard to think of any other product where mistakes can result in it becoming more valuable than a perfect example! [excerpt]
