Though several stylistic details have survived since the earliest days—the use of the stars, pointing hand, and Greek letters on the obverse, for example—notable differences exist between older keys and current examples. The name of the recipient was not engraved on the earliest fobs or keys, and was not until the first decade of the nineteenth century. The name of the school from which the fob or key came was also not routinely included on the earliest models, and sometimes the only way to trace a key to a particular school's chapter is by researching the name of the recipient against surviving class records. The number of stars on the obverse has also changed over the years, with never fewer than three, but on some known examples with as many as a dozen (the explanation as to the meaning of the stars in these early cases varies from chapter to chapter). Also, the date of the awarding of the honor is only seen on keys from the second quarter of the nineteenth century onward (some people mistake the date that appears on the fob or key—December 5, 1776—as the date that a particular fob or key was awarded, when in fact it is merely the date of the founding of the society). Only in 1912 was the key made to a uniform standard of size, golden appearance (some are plated), and engraving with the school's name, recipient's name, and date of the award.
