The mother states she saw her child swallow a quarter over 1 day prior to presenting to your Emergency Department. The mom denies other symptoms or changes in the child's behavior including drooling, pain, shortness of breath, vomiting, or fever. In your ED the child is asymptomatic and in no apparent distress. You obtain an x-ray which shows a coin lodged in the esophagus.
