Messrs. Editors:--The writer of the communication, published in the Centinel of Saturday last, over the signature of C., is in error respecting the real value of an eagle, coined after the 31st of July, 1834, being ten dollars and nineteen cents, instead of $10. The present standard value of gold, coined in the United States since the late law went into operation, is, according to the decision of the director of the mint, and also according to "Bicknell's Gold Coin Chart," 21 carats 2 14-43 grains. By the following rule the contents is pure gold can readily be ascertained.--An eagle must, by the law, weigh 258 grs. or 10 dwt. 18 grs. 
 
 

American gold, coined before August 1st, 1834, is valued at 9 48-10 cents to the dwt., or 25 6-20 grs. to the dollar, coined after July 31st, 1834, at 93 cents to the dwt., or 25 3-4 grs. to the dollar. 

By publishing the above you will probably give your readers some light upon the subject, and will oblige  T. B. R. 

[We have not understood our correspondent C. to bring in question the relative weight of the two coins. His only object, as we understand it, is to ascertain by what authority standard gold has been debased from 22 to 21 1/2 carats. If there be no authority for it, then the new coins not conforming to the law for regulating the mint, will not be U.S. money nor a legal tender]
