The most notable coin in this case, and perhaps the most celebrated coin in the world, is the “Widow’s Mite.” Its name bespeaks its commercial insignificance. Yet visitors every day, upon entering the Cabinet of the Mint, ask first to see the “Widow’s Mite.” The following letter from Wm. E. Du Bois, will be found of interest to the reader. THE WIDOW’S MITE. SIR: The curators of the mint cabinet do not consent to the intimation in a statement recently made that their widow’s mite is not the real coin. The expression of a doubt as to any received fact is thought to be a sign of superior insight. Hence we have so much “destructive criticism,” a good deal of it being fatal to the critic himself.
