Did you examine your paper money closely?See if you can locate a $5,$10,or $20 bill printed before 1964 and marked "Federal Reserve Note" over the portrait.In the upper left portion above the seal,a staement witten in fine print says that the note is a legal tender and that it is redeemable in lawful money at the United States Treasury ,or at any Federal Reserve Bank.Does this mean that the bill is not lawful?At the button center the same Bill says,"Will pay to the bearer on demand X dollars."Does this mean that your X-dollar bill is not X dollars?
呵呵,我明白大致意思了,可惜的是分既要不回,再牵强地送人也总得有个理由吧?
