Curbside coin collector
I believe the answer is:
meter
'curbside coin collector' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for meter that I've seen before include "Device for measuring and recording" , "Poe sometimes used this" , "Device for recording, say, usage (5)" , "Gauge" , "Measuring device, say for electricity usage" .)
