In the early 9th century, a three-fourths-weight solidus was issued in parallel with a full-weight solidus, both preserving the standard of fineness, under a failed plan to force the market to accept the underweight coins at the value of the full weight coins. The 11⁄12 weight coin was called a "tetarteron" (a Greek comparative adjective, literally "fourth-er"), and the full weight solidus was called the "histamenon". The "tetarteron" was unpopular and was only sporadically reissued during the 10th century. The full weight solidus was struck at 72 to the Roman pound, roughly 4.48 grams in weight. There were also solidi of weight reduced by one "siliqua" issued for trade with the Near East. These reduced solidi, with a star both on obverse and reverse, weighed about 4.25 g.
