Danvers' Peabody Institute Library shared a Facebook post on Wednesday, saying several customers had tried to pass off tokens from local arcade chains as actual currency when attempting to pay late fines or printing fees.

Since they are not legal tender, we cannot accept them," the library said. Bookkeeper Sue Kontos said she discovered the three Chuck E. Cheese's tokens and one Bonkers token while sorting through the library's change. "Somehow, their coins turned up in the rest of the cash," Kontos told the Salem News. "Everyone got a laugh out of it." Library director Jennifer McGeorge said the size and shape of the game tokens makes them easy to confuse them with with actual money at first glance. "They are the size of quarters, so you have to pay attention," she said. Although the librarians were amused by the unorthodox payment trick, they sought to remind patrons that only actual U.S. currency will actually be accepted.
