Clarity please

Bingo! What matters is who issues the "money". The treasury of the US or A private bank. Lawful money of the U.S. (coin or US currency notes) or Bank credit (Lawful money).

Notes, bills, and coins issued by the U.S. Treasury (actually .... the Department of the Treasury) is lawful money.

Notes and bills issued by the FRB is legal tender.

US Treasury bills and notes are used as a reserve currency, but not a circulating one.

Also, don't you find it strange that the article 'the' is in the official title?

Strangely enough, I've heard that postal money orders are lawful money.
