Girl Scout leader Dianna Mines got an unpleasant surprise when she tried to deposit the $258 her troop had collected selling cookies.
A TD Bank teller told her that four of the $20 bills in the deposit were counterfeit, the Lowell Sun reported.
"I was shocked," said Mines, who heads Troop 60916 in Tyngsborough, Mass. "Girl Scouts is about trying to teach the girls how to be good members of the community. To be taken advantage of was just not right."
Mines and her 21-member troop had earned the cash selling cookies outside a Walmart in Hudson, N.H. March 4.
Mines said she has not filed a police report, but added that she probably should have and still might.
The troop was raising money for a hiking trip to Rowley in May and a Cape Cod meeting of troops from across Eastern Massachusetts in June to celebrate 100 years of Girl Scouts.
She said the staff at TD Bank were nice enough to buy a few boxes of cookies when they heard the news.
