Don't take any wooden nickels
Meaning
Be wary and do not let others deceive or take advantage of you.
Origin
Imagine the hustle and bustle of early 20th-century America, especially during the lean years of the Great Depression. Real money was scarce, and sometimes businesses or towns issued "wooden nickels"—promotional tokens or temporary currency with no actual value beyond a very specific, limited use, if any. An unscrupulous person might try to pass one off as real money to an unsuspecting buyer or seller. This literal act of being handed something worthless in place of real tender quickly evolved into a powerful idiom. It became a sharp, street-smart warning: stay alert, be discerning, and don't let anyone trick you into accepting something of no value.
Examples
