About this set: Like other collectors of his time, the famed Louis Eliasberg often collected proofs as his examples of Philadelphia issues. In those days, it was common for collectors to consider proofs as "better" examples of an issue than their mint state counterparts. (Similarly, even earlier generations of collectors did not consider mintmarked coins as separate issues to be collected, and so they collected date sets.) Of course, nowadays we consider proofs and business strikes to be two distinct issues, and we collect them separately just as we do mintmarked issues. Therefore, while the spectacular and legendary Eliasberg collection included a complete set of Barber quarters by date and mintmark, he had no business strikes from the Philadelphia mint except for the 1916, as that was the only year from 1892 to 1916 in which proofs of this design were not struck. Here then, just for fun, is a display of "P" mint business strikes - including all the coins Eliasberg was missing 1892 to 1915. Registry buffs - note that this set contains only P-mint coins; Sunnywood could have scored an even higher ranking by including coins from other mints.
