Bill is one of the hardest-working people I've ever met in the business. At any given time, he has 70,000 listings on
ebay - by far the most that I can determine, of ANY seller in the United States Stamps catagories. He also is extremely knowledgeable and possesses keen eyes and abilities to judge the value of just about any United States material. Aside from his monsterous
ebay presence, he regularly attends virtually every stamp show in the U.S. as well as nearly every public auction of an importance. He also attends coin and banknote shows. In short, he is indeed one of the most talented dealers of this generation.
But............... I will let others tell the "other side" of the story (as has been done here and on other discussion boards several times or more) in the past.
